These are all legal and have nothing to do with RDFa. (Some of these may also disappear from the HTML5 document.) The same holds for rdfa-1.1 core document 

was specifically speaking about http://dev.w3.org/html5/rdfa/ which has 
54 - or is that not covered by this wg at this time or? (I could be 
missing something) - rdfa-core is already absolute minimum, the 
xhtml/xml docs can mention as much as they want imho.

>> RDF caters for lang, some RDFa Host environments do, we've catered for it minimally in RDFa core such that if encountered, say xml:lang or lang in xhtml, then it can be used, otherwise it is unhandled. That is to say, it's not an RDF Core attribute, and usage is delegated to host languages. Fair summary?

ahh yes - likewise, it's very general, I'll see if I can draft some kind 
of something for it.
