Re: RDFa Lite and non-RDFa @rel values

Perhaps the way to address unwanted @rel terms expanding because of @vocab is simply to say that, for HTML+RDFa, @vocab is not used to turn terms into IRIs, and so anything that's not a defined term causes the @rel to be dropped.

This only affects HTML+RDFa 1.1, so does not address a CR change to RDFa 1.1 Core.
