Well, as Shane suggests, that's what the hypertext coordination group  
(HCG) is there for. As Shane pointed out RDFa has gone through the W3C  
process, which includes announcing last call to the HCG, and making sure  
that groups register interest in commenting.

Well, RDFa is being implemented as we speak too. At least RDFa followed  
process and made sure that we had agreement on features before  
implementing them. Ignoring W3C process and then saying "it's implemented  
already, we can't change it now" is a guaranteed way to create this sort  
of problem.

In the meantime you can use the XHTML+RDFa doctype to get it to validate.
