Not really convinced, chiefly for reasons of separation of concerns. Given that throughout the pipeline the XML is being held in java's unicode strings, IMO the only component that should need to worry about the charset being used to serialise the output should be the serialiser that's doing it, otherwise you can end up with a document using one charset that claims inside to be a different one. If you're happy to leave it to the serialiser to insert the PI in the output (including the charset) rather than having it already in the pipeline's XML stream (e.g. inserted by xsl:processing-instruction in an XSLT template), and happy to let the the HTML serialiser insert the doctype rather than having it already in the pipeline's stream, then why shouldn't the HTML/XHTML serialiser also insert the meta tag specifying the charset? In an ideal world, we wouldn't even have to specify a particular encoding on the serialiser either - there'd be a default configured somewhere, but it would select an appropriate one dynamically at the time of output based on the Accept-Charset request header sent by the browser... and why should the earlier part of the pipeline also need to worry about that?

RE: HTML5 serializer
Hi Thorsten, I assume with prior transformation process you are referring to the transformerhandler which insert the meta tag for the html use case. I also just stumbled across Michael Kay's reponse about serialization for html5 where he mentions: "The XSLT and XQuery WGs have taken the view that we will address serialization to HTML5 when HTML5 is finished; meanwhile WHAT WG seem to be claiming that "finished" is an obsolete concept and that HTML5 will remain under continuous change forever. Perhaps I'm misquoting them, but that's my understanding." http://www.biglist.com/lists/lists.mulberrytech.com/xsl-list/archives/201105/msg00067.html But to wrap up what I'm trying to achieve here: I want to be able to do following use cases: * XML data --> transform using xslt to html5 --> serialize to html5 * stringtemplate generator --> serialize to html5 Preferably I want to be able to do so out-of-the-box with Cocoon3. As you seem more acquainted with the topic what would need to be done to enable this?

RE: HTML5 serializer
Hi Thorsten, Adding in general is not a concern faik but setting the correct encoding is. Examples are for xml files And for html files So I was only referring to setting the correct encoding which can be configured as a Serializer property.

RE: HTML5 serializer
Hi Sylvain,
Thx for the pointer.
Using the same test but with some changes to the html5serializer
public static XMLSerializer createHTML5Serializer() {
XMLSerializer serializer = new XMLSerializer();
serializer.setContentType(TEXT_HTML_UTF_8);
serializer.setDoctypeSystem("about:legacy-compat");
serializer.setEncoding(UTF_8);
serializer.setMethod(HTML);
return serializer;
}
now results in
serializer test
test
So we're almost there. Do you have any suggestion how to accomplish using the
correct ?? Or do you think that's not worth the
effort?

RE: HTML5 serializer
For all I know the serializer does not actually output anything directly. It
hands over the task to the transformerhandler and this is where the culprit
resides.
There is no need to extend the current serializer if I adapt the current way
of working.
XmlSerializer, Html4Serializer and XhtmlSerializer are all just XmlSerializers
with a different set of properties and the current XMLSerializer class
provides static methods to create them. It makes much more sense to add a
static factory method for a html5 serializer there as well.
The problem is that currently to actually have the transformerhandler output a
doctype declaration you do need to pass I think a doctypepublic property but
this cannot be empty from the looks of it:
public XMLSerializer setDoctypePublic(String doctypePublic) {
if (doctypePublic == null || EMPTY.equals(doctypePublic)) {
throw new SetupException("A doctype-public has to be passed as
argument.");
}
this.format.put(OutputKeys.DOCTYPE_PUBLIC, doctypePublic);
return this;
}
public XMLSerializer setDoctypeSystem(String doctypeSystem) {
if (doctypeSystem == null || EMPTY.equals(doctypeSystem)) {
throw new SetupException("A doctype-system has to be passed as
argument.");
}
this.format.put(OutputKeys.DOCTYPE_SYSTEM, doctypeSystem);
return this;
}

Hey Robby,
which Cocoon version are you using for your project? In C2.1 and C2.2 there's
not only a XMLSerializer but also an HTMLSerializer and XHTMLSerializer for
their specific needs. So why not create your own HTML5Serializer?
In HTML5 the specification teams tried to specify what browsers were already
doing instead of making a new theoretical specification. HTML5 should be
backwards compatible with previous (X)HTML versions. This is the reason why
some old elements are not deprecated but considered obsolete (remember marquee,
it was so cool on Geocities).
The doctype doesn't really matter, browsers generally ignore the PUBLIC part in
the doctype (apart from some hacks in IE going into quirks mode).
