My general take on this is that our transformation language of choice 
(XSLT) is quite capable of allowing the algorithms themselves to determine
  how to do context-sensitive extraction using 'push' [1]  mechanisms 
rather than having GRDDL contend with this.

I'm not sure I follow what the conflict is with embedding RDF/XML directly especially
  since we have transformation algorithms for extracting RDF/XML from arbitrary
  locations within its containing document.
