However, one thing _really_ bugs me: Our nice (X)HTML+RDFa documents are
ignored by 'Semantic Web search engines' as ptsw [2] or sindice [3].
People, move on!

Also Semantic Radar [1] may be involved in it and the most simple way
is to use DTD itself to identify an RDFa.

Actually, a @profile would be the most simple way to indentify RDFa ;). I  
don't think there is any cross-browser javascript, or xslt, way to check  
for a DTD.

Also, when  RDFa is finished, will there not be several DTDs (for each  
supported version of HTML/XHTML)? Whereas there only needs to be one  
profile.

(profiles are also useful while the syntax is still being finalised, as  
documents can link to the transformation that matches the syntax they  
used.)

Admittedly, it is easier to check for a specific DTD (or @profile), than  
for arbitrary @profile uris, and following them to see if they are  
GRDDLable, but if a tool such as semantic radar or ptsw does so, it would  
be able to find more RDF (such as eRDF and GRDDL-enabled microformats).

Anyway, sorry, I'll stop harping on about it now.
