Here's another option that I thought of this morning.

Option #3: RDFa processors honour @rel as usual, but RDFa documents are
non-conforming if rel is used with a non-CURIE, non-URI token within
the scope of @vocab. Conformance checkers MUST report this.

This way document authors get told about the potential ambiguity, and
are required to resolve it to achieve a conforming document, and RDFa
parsing is consistent between XHTML+RDFa and HTML+RDFa, which helps
people who want to author polyglot XHTML/HTML content.
