Since both roles and microformats are open extension mechanisms, it's a
moving target and specifying rules of precedence would become harder and
harder, and impose a greater and greater burden of testing on extension
spec writers, as more and more roles and microformats are added.

One way to manage this complexity would be to group roles and
microformats into /types/ and set rules of precedence for those types.
Which could be done, but I don't see anyone doing it.

It doesn't seem obvious to anyone over on the microformat list, AFAICT.  If
it is that critical, why are all those to whom it is obvious making the case
on uf-discuss?

Unfortunately, this aspect is not my highest priority.  The unfortunate
thing is I'll probably just have to knowingly generate invalid HTML in some
cases because I know the browsers will handle it, as will so many others who
are using semantic markup in HTML who bump into the limitations imposed by
the specification writer.  FWIW.

Conflicts don't create any anxiety for me. If there is a conflict either
there is an undefined state or one of the two is defined to take

Right. Do you volunteer for the job of going through all "role" values
and all current HTML element semantics and define which one takes
presedence in each possible conflict? Matthew's point is that this
task itself is massive. Imagine: for each suggested "role" value, go
through all HTML elements (since "role" is a global attribute) and
note possible conflicts. Go through all other HTML attributes (and
their values) and note possible conflicts. Now define the outcome of
each conflict. Do it again, but now in C++ code.
His secondary point is that if the spec doesn't do this, every browser
will handle things differently so authors will not be able to use
"role" as intended because of browser incompatibilities.

Then your beef should not be with me, but with the W3C (or similar). If they
will publish a finding that says it's a bad thing, I might come to see it as
such.  Right now I don't.

It is NOT fallacy as the entire point of the W3C and IETF and others is to
develop consensus between Good and Bad Things so we have some Authorities
and don't have to debate our PERSONAL OPINIONS ad infinitum.  If you think
it is wrong, take it a group that will agree and publish a finding. Or
create an advocacy initiative (like I have: www.welldesignedurls.org) and
publish enough of your work in a compelling enough manner that people will
agree to support your position.  As it is, your position is just a judgement
call that can only be determined with individual experience to which I
currently disgree, but please don't call me out on my position in a public
forum because you have an opinion that few if any others are rallying
behind. 

Even better, why not go to [uf-discuss] and make your case there?  If you
can convince those guys it's not a good idea you'll be far more effective
then trying to convince me here (where few others on *this* list seem to
care.)

I can debate each of your remaining points from your message, but it is
hardly relevent because it won't change your mind or for that matter anyone
else's on this list.  At a high level you seem to feel that everything
should be tightly controlled so there is no chance of invalid combinations
and I believe at a high level things should be loosely controlled even if it
means some invaldid markuo sp that useful patterns are allowed to emerge.
You prefer control, I prefer freedom.  If we were talking politics you'd be
right-wing and I've be left.  Since it is a fundamental disagreement in
philosophy which doesn't necessarily make either of us more right or wrong
than the other, neither of us can really claim the high ground.  

If you feel strongly about your position, take it to the W3C, uf-discuss,
the IETF, or all of the above and make your case so that they publish a
finding in support of your position.  Until then, I don't think it's
appropriate to continue discussing on WHATWG.  If others on the list
disagree and think we should continue the debate here, they should let us
both. Until then, adieu.

   Interesting that you should choose that example, because it can mean
different things depending on the element you use it on. Therefore, a
global |type| attribute would almost certainly conflict with the
element-specific attribute unless it was defined otherwise.

   One thing an element like |type| does provide, however, is mutual
exclusion. However, you could do that with a namespace:

| 

   For |role|, you're required to use namespaces anyways, so I don't see
how |role| brings anything to the table. It's just a means of creating
minimized boolean attributes in XML. I'd much rather see XML modified to
accommodate minimized attributes because I suspect the additional
parsing of the attribute value would be just as burdensome.

   Now, remember this example?

   Let's take out the conflicting roles and add a check state:

   It could be eliminated by using a mutually exclusive attribute:

actually requires fewer characters. In theory, if you used a lot of
roles, the savings in equal signs and quotation marks might make |role|
more attractive, but I doubt it would be significant to justify |role|
itself.

   Even then, though, you have to determine how the attributes interact
with the element they're assigned to. Does |wai:widget| override the
 element's |type| attribute? Or its |value|? How does this
attribute integrate into the form submission model? How would I use this
attribute with XHTML 2.0 and XForms? Every time you introduce a new
namespace, you have an entire set of elements for which you have to
define interactions with other namespaces.

   I've shown you that not only are there conflicts with proposed
attributes, roles and elements, but that they actually compete in
certain situations. Furthermore, I did so with only minutes worth of

   This line of conversation doesn't advance our conversation regarding
global attributes and roles. Even if there is no support for my

logical fallacy.

   Because markup structure has semantic significance. If you shift all
the semantic meaning to global attributes, you loose the ability to use
structure for semantic purposes.

   There are people who posted ideas about semantic properties for CSS
on the www-style mailing list. They would likely be ecstatic about
turning CSS into a cascading semantics language. Personally, this would
be a greater nightmare than the |role| attribute.

   However, global attributes like |role| aren't much better. Attributes
should specify the details of semantics that elements already possess.
For example, |type| on an  element specifies the type of input.
One of the example of the |role| attribute shows how you can provide
values like "checkbox" to elements like . I can understand
assigning values such as these to DHTML container elements for
accessibility purposes (and that might be a legitimate reason to create
something like a global "accessrole" attribute or something similar),
but |role| does not define any such limitations.

   Generally, though, this is just math. For every attribute or role you
have that can apply to ALL elements, you have the semantics of all those
 elements to interact with, plus you have interactions between an
indefinite number of global attributes that may be defined on that
element. Without some sort of scope limitation, you can't possible
define how the semantics of everything interacts. Think about the
conversation regarding how simple nested elements in HTML interact with
their parents and increase the complexity by several orders of magnitude.

I'd suggest the emphasis on text in much current web content is is
itself a product of the comparatively poor transfer rates of audio and
video: a situation that the growth of broadband telecommunications is
changing rapidly. Certainly many people struggling with Blogger and
MySpace markup might be happier with pod and video casting. Conversely,
one of text's major advantages is its greater susceptibility to
machine-processing and hence "free" accessibility.

I'm not entirely sure what "non-heuristic machine consumption" is, but,
given the lack of agreed microformats for these things, I'd say their
usefulness is practically untested. (And given the limited market
penetration of the microformat "idea", I wouldn't conclude anything from
the non-existence of related microformats. We haven't even got hCite off
the ground yet, and the market for that is massive.)

On the quotations front, I'd argue this is largely the fault of W3C spec
writers for:

1. Failing to suggest behaviour for the CITE attribute; consequent chaos
described at:

http://lists.w3.org/Archives/Public/www-html/2006Nov/0053.html

(Web Applications 1.0 fixes this (a suggestion about how to avoid
conflicts with anchor links would be good though). XHTML2 doesn't.)

2. Failing to suggest how to connect CITE to Q and BLOCKQUOTE in a
machine-readable fashion. (Web Applications 1.0 fixes this. XHTML2
doesn't.)

3. Failing to pay any attention to real print typography of quotations
(where the host language usually determines punctuation, not the quoted
language). (Web Applications 1.0 currently dodges this question by not
discussing delimiters. XHTML2 completely confuses the issue by allowing
both in-text delimiters and stylesheet delimiters, even though neither
currently covers the range of quotation punctuation. So not fixed
anywhere really.)

4. Failing to provide adequate facilities for styling Q. (/Still/ not
fixed in CSS3.)

In addition to W3C, we can also blame Microsoft for 1) not including Q
in MSAA (fixed in IAccessible2, not sure about UI Automation) and 2) not
generating quotation punctuation in IE as per the HTML specification
(still not fixed in IE7, and while they've made noises about fixing it
in IE8, they haven't yet fixed their erroneous MSDN documentation
either)

One has to eliminate those key factors from the equation before you can
begin to use past evidence to assess whether authors would be happy to
use Q, and whether any one would machine process it. (Actually the
Window-Eyes screen reader already can report Q; and the Fire Vox talking
browser will in the future.)

That was uncalled for.

The point is that there are limited ways of communicating data to

hopelessly bad data transfer rates, so it isn't practical to design

Can you please explain exactly what you mean about "semantic styling

I totally agree. HTML should be describing documents in a useful

it does not reduce the capabilities of the language to correctly

But IMHO "independence of one client device or presentation media" is
not /the/ goal of eschewing presentational markup, but rather only one
such goal. It's trivial for a screen reader to report presentational
information such as . Disambiguation and ease of restyling are just
as important. The same presentation can mean multiple things. Semantic
markup disambiguates between , , , and so on. This
helps with machine processing and human understanding. And if you want
to change italic citations to bold citations, then you don't have to
distinguish the citations from the non-citations by hand. You just put a
different rule into your stylesheet.

FWIW, it seems that a better term for the concept you describe would be
"semantic binding language", since presentation isn't actually involved
anywhere. In the same vein CSS would be a "presentation binding language" and
XBL roughly a "behavior binding language". Having said that, I'm not sure I

I think what's wanted is a Cascading Semantics Language. Its syntax
could be based on CSS. For example:
.masthead {
 type:heading;
 strength:high;
}

.division {
 type:heading;
 strength: normal;
}

.flow {
 type:body;
 strength:normal;
}

.aside {
 strength:weaker;
}

Behaviours, script bindings, etc could be mixed into this.

To be honest, I still don't understand this explanation. Is this a
roundabout way of defining a "semantic styling language" as an (X)HTML
that uses (X)HTML attributes as well as elements to express meaning?
(Which is of course true of HTML 4 already, and even more true of the
proposed XHTML 2.)

I don't see how that matters at all. It seems to me that what's crucial
is that if authors are going to /rely/ on any semantic elements or
attributes, that user-agents should be guaranteed to express those
semantics to users in a usable fashion. This is my central worry about
microformats, especially when people starting trying to hide data within
attributes rather than exposing it as text content, and it is also my
central worry about XHTML2's role module.

No idea. What happens with http://www.example.com";> ?

No idea. What would Foobar mean?

Now /that/ is a real problem, but it is little different in type to
specifying what elements contain, or can contain, what other elements.

   A "presentational markup language" would be like SVG or X3D. They use
markup to create a presentation that may or may not be meaningful. HTML
is a "semantic markup language". It generally doesn't define how to
present an element. Instead, it defines the what that element is
supposed to mean in an abstract sense.

   A "semantic styling language" would be a language to assign semantics
to elements in a manner similar to how CSS controls their presentations.
One could change attributes like |href| and |rule| into style sheet
properties and they'd still work in the exact same way, except that you
would be able to use selectors rather than placing them on each element
individually. This is what I meant by my insensitive "half-a**ed"
comment. If you're going to do semantic assignment in a global fashion,
wouldn't you rather select entire categories of elements and assign a
set of semantic properties to them all at once?

   As powerful as this is, though, I strongly oppose it for two reasons:

1) HTML elements themselves would no longer have any meaning. They would
just be targets for semantic property assignment. Think about what
happens to the  element if |href| allows every element to be a hyperlink.

2) Semantics can interact in ways presentation never could. For
instance, what happens when you put |href| on an  element? What
does  mean? When attributes (or properties) are global,
every element has to define who it interacts with that property. The
number of interactions grows exponentially. (This is also a problem with
microformats that don't specify what elements certain classes, et
cetera, can be used on.)

   Markup for semantics AND presentation? That would be the  and 
elements. ;)

   I'm not always the most tactful or sensitive person. If my choice of
words in my original message offended you, I apologize. My passion for a
subject occasionally makes me blind to how others might interpret my
message.

   However, that does not excuse your behavior. You talk about how
showing respect, but you're not willing to show it yourself. You avoid
debating the subject of my original message, while replying _only_ to a
perceived slight. You do not encourage an atmosphere of respect, so stop
pretending to be its champion.

   If you really want to debate the original topic, I'll be waiting. I'd
be pleasantly surprised if this actually turned into a discussion about
semantic styling languages, but I'm not holding my breath.

Based on the language you chose, that wasn't clear to me at all. Let me
quote:

Maybe your is a use of language is different from that which I am not
familiar, but as I read it, "you" referred to me.  "You" can refer to the
collective, but your context didn't support that intrepretation. And the
"you" wouldn't have been bad had you not included the "half-a**ed
unconscious attempts" as part of your closing statement. As such, even if
you did mean "you, collectively", I still find it disrespectful.

I didn't intend for it to be; I was responding as I was responded to.

However, out of respect for everyone else on WHATWG this will be my last
comment on the list regarding the above issue.  If you want to debate the
merits and non-merits of adding semantics to HTML, or "semantic styling
languages" as you call it, I'll be more than happy to in a mutually
respectful context.

   I think it's clear from the context of my previous message that I was
neither referring specifically to you, nor did I make any claim to know
your thoughts. My claim was that you and others were pushing new
features that collectively amounted to a semantic styling language
without realizing it. If anything, that's believing I know what group of
people are _not_ thinking.

   There's nothing respectful about the tone of your reply. If you
wanted to constructively criticize my previous message, you could have
simply emailed me directly. What you're really trying to do is publicly
shame me, and that's not something you do to someone you respect.

I may not like that you disagreed with me, but what I far less is for
someone to talk down to me in a public forum based on their *assumption*
that they know what *I* am thinking.

A more respectful approach would have been far more productive.

Sorry to interrupt, but I don't understand what this phrase means. How
would you define a "semantic styling language" differently from a
"semantic markup language", a "presentational markup language", and a
"markup language for semantics and presentation"?
