Could this be something to do with this issue :

http://www.w3.org/2000/03/rdf-tracking/#faq-html-compliance

Summary: The RDF FAQ suggests how RDF meta data might be included in HTML.
The suggested approach is fails HTML 4.01 and XHTML validation.

<- Right!!  And where the URI is a URL to a web page, the best way
<- to do that
<- is simply to embed the RDF description of exactly what the
<- author intended
<- the URI to denote right there between <head> ...</head>.
<-
<- The strange thing, that I can't figure out, is: even though the W3C
<- recommends this (see quote form M&S below ),  one can almost
<- never find such
<- descriptions on their pages.
<-
<-    Why?
<-
<- Of course, we also need a good schema that would deconfuse these
<- use\mention
<- terms like "denote", "name", "reference", "describes", "models", "sinn",
<- "bedeutung"  .....
