Sure, that sounds good. The way I've structured my RDFa parser is that
it can take any number of "hGRDDL" transformations, one of which is
"XHTML1 reserved values". Note that I can easily have that also handle
<meta name=> if we want it to.

The point is that it can trigger a different set of reserved values
depending on the version of XHTML. We know what the reserved values are
for XHTML1, and they can be expanded for XHTML2, 3, etc...

Certainly, in the RDFa spec, we should "outsource" the definition of the
reserved words to the XHTML spec.
