Support for RDFa in HTML5

Message-ID: <CA5EFD1C.110E8%aykut.sensoy@bild.de>
according to the W3C Specification:

1. the xmlns attribute has been replaced with the prefix attribute in HTML5

example: <html prefix="rdfa: http://www.w3.org/ns/rdfa#">

2. the RDFa declaration must be defined with the version attribute in HTML5

example: <html version="HTML+RDFa 1.1">

Complete example:
<html version="HTML+RDFa 1.1" prefix="rdfa: http://www.w3.org/ns/rdfa#">

But both attributes are not supported in the W3C HTML5 Validator.
I would like to know if these attributes will be part of HTML5 Validator or is there another valid method to integrate RDFa into HTML5?

Kind Regards
