Dear Sam,

I cannot comment on Oxygen, because I have never used it. But, for
example, the file:

http://www.w3.org/2001/sw/sweo/public/UseCases/Faviki/Overview.html

- validates with the W3C validator (which also means that it is valid
xml, ie, Oxygen should not have a problem with it...)
- it does not contain a <style> element but it definitely could
- has, for example, a &gt; entity somewhere in the text
- refers to the foaf, dc, bibo vocabularies
- and it definitely generates the RDF via RDFa, see

http://www.w3.org/2001/sw/sweo/public/UseCases/Faviki/Overview.rdf
http://www.w3.org/2001/sw/sweo/public/UseCases/Faviki/Overview.ttl

both are generated on-the-fly via an RDFa distiller.

Ie: what I would like to know is what made you think that this would not
be possible?

Cheers

Ivan
