Yes, what Benjamin and Ian said.

Additionally, HTML5+RDFa spec does not support the @version attribute in
HTML5+RDFa:

"The version attribute is not supported in HTML5 and is non-conforming.
However, if an HTML+RDFa document contains the version attribute on the
HTML element, a conforming RDFa Processor must examine the value of this
attribute. If the value matches that of a defined version of RDFa, then
the processing rules for that version must be used. If the value does
not match a defined version, or there is no version attribute, then the
processing rules for the most recent version of RDFa 1.1 must be used."

It also should be possible to write a parser implementation that is
capable of complying with both the HTML5 specification and the HTML+RDFa
specification. You may want to read the latest HTML+RDFa specification
for details:

http://www.w3.org/TR/2012/WD-rdfa-in-html-20120315/

If after reading the explanation and document above, you still do not
think this is possible, please explain exactly what you feel is not
possible and why.
