Holy grail

Dear all,

This is my first post to this list, so please be forgiving :)

I would like to be able to write an XHTML+RDFa document that:

   - validates in Oxygen (or other programs using Xerces for validation),
   and
   - validates in the W3C validator, and
   - is capable of containing <style> and <script> elements and other valid
   XHTML Strict elements, even if they do contain whitespace*, and
   - is capable of containing (X)HTML entity references such as &hellip;,
   and
   - is capable of containing me to use elements from FOAF, DC, etc, within
   the document, by using those languages' namespaces as appropriate.

As far as I can tell, such a thing is not currently possible, but I hope I
am wrong!

Please could you let me know whether I am wrong or not, and if I am, please
could you present me with a sample document that demonstrates the
possibility of meeting the above criteria?

Many thanks indeed,

Sam

*I'm referring to the problem of the xml:space attribute being set to "(
preserve )" for the <script> element in
http://www.w3.org/MarkUp/DTD/xhtml-script-1.mod, (and I think the <style>
element's in a similar position) which leaves - if I'm not mistaken -
http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd at odds with
http://www.w3.org/MarkUp/SCHEMA/xhtml-rdfa-1.xsd. See
http://www.oxygenxml.com/forum/topic2603.html for some discussion of the
issue.
