In a nutshell, in XSD 1.1, first allow any attribute in the content

XMLmind XML Editor which is grammar-driven.

Limiting ourselves to XSD 1.0 only, then, by permitting any attribute
and setting processContents to "lax", the validator will check the
predefined attributes for validity - but as well allow undefined
attributes.

I have checked that the above works in Xmplipfy

For instance it barks if I do this: <hr hidden="hid" data-foo="bar"

But it is silent if I do this: <hr hidden="hidden" data-foo="bar"

Could this also work in XMLmind XML Editor?
Don't know. I need to test this to give you answer. However, the
solution you suggest, foreign wildcard attributes intersecting the
"normal attributes", is not adapted to the design of XMLmind XML
Editor. See below.
Looking forward to your testing. ;-)

Sorry but the solution you suggest, foreign wildcard attributes
intersecting the "normal attributes", is not adapted to the design of
XMLmind XML Editor.
Note that everything you said about "what about the possibility of
allowing more" already works fine, but using foreign *namespaces*.
Had the (X)HTML5 designers chosen "data:" prefixed attributes instead
of "data-" attributes, there would be no problem at all as XSD and
RELAX NG can express this (assuming that in this hypothetical
(X)HTML5, prefix "data" is bound to a namespace different from
"http://www.w3.org/1999/xhtml";).
Judging from the examples given e.g. in the "official" XSD 1.0 primer,
it seems like foreign namespace unknown attributes is what one has had
in mind.
Yes, I know, "data-" attributes exist for historical reasons.
I’m not certain what you refer to. I did not contribute in the debate,
I think, when data-* was added to the HTML5 spec. The only "history" I
know is that for HTMl5, there was much opposition to foreign namespace
extensibility. The status of data-* attributes is also a little bit
adhoc it is mean to be an adhoc attriubute.
