Which xhtml serializer are you using? The default one configured in the
main sitemap distributed with Cocoon (which is just the XMLSerializer
with a special doctype configured), or the XHTMLSeralizer from the
serializers block? I'm guessing the former.
Remember that just adding an XHTML doctype to a HTML document does not
make it XHTML. It also has to be well-formed XML, and be in the
http://www.w3.org/1999/xhtml namespace. My hunch is that your content,
though well-formed, is not in the XHTML namespace, so the browser does
not recognize those elements as HTML and therefore does not apply the
default styles that are normally applied to HTML. This is why the page
layout "breaks" as you say.
Getting your CForms content into the XHTML namespace is a little tricky
since the forms-*-styling.xsl transforms produce output in the null
namespace. So you need something that changes that output into the
XHTML namespace.
There are two options I know of for this:
1) Add a transform before the serializer that changes the namespace of
all elements... could be something as simple as a single template:
<xsl:template match="*">
<xsl:element name="{local-name()}"
namespace=" http://www.w3.org/1999/xhtml">
<xsl:copy-of select="@*" />
<xsl:apply-templates />
</xsl:element>
</xsl:template>
2) Use the XHTMLSerializer from the serializers block. This serializer
adds the XHTML namespace to un-namespaced elements automatically. In
addition it also does other XHTML-specific things like making sure
<script></script> tags are not collapsed, so I would recommend this
approach.
Once you've got that working, you will need to be aware that changing to
a strict XHTML doctype will trigger strict mode in certain browsers, so
you will need to be much more careful about other things as well, such
as the mime-types of supporting CSS files and differences in the DOM for
scripts. In fact I'm not sure if the Dojo/AJAX code even takes those
DOM differences into account.
Also, and this is a pet peeve of mine: the CForms AJAX framework
currently does not produce valid HTML/XHTML, in that there are some
custom attributes used to support the AJAX code (dojoType="CFormsForm"
on <form> in particular) which will prevent the document from
validating. Which begs the question: why are you trying to produce
XHTML in the first place? If it's an attempt to enforce some sort of
stricter document validation then you're going to have trouble.
...
OK, so I just gave it a quick try, using the XHTML serializer from the
serializers block. The page style/layout is fixed, but it turns out
those DOM differences I mentioned earlier are indeed causing problems in
the CForms/Dojo client-side _javascript_ code. I'll be submitting a patch
soon for some of them, hopefully I can fix them all. But in the
meantime, you need to know that it won't work out of the box. Sorry!
