I would not be opposed to adding text in the RDFa in HTML definition 
like "prefix names SHOULD be defined in lower-case to help ensure 
maximum portability among parsers, since it is common for DOM-based 
parsers to not preserve the case of attribute names."

I don't see there being any need to change the definition of XML-based 
languages like RDFa for XHTML.  After all, in XML case is preserved.  Or 
is ot someone's goal that documents be able to be parsed as EITHER XML 
or HTML?  It's not my goal.  If I define a document using an HTML family 
language, I expect it to be parser using an HTML family parser.  If I 
define it using an XHTML family language then I expect it to be parsed 
using an XML-conforming parser.  Such a parser would preserve the case 
of element and attributes.

Right?
