Exception on @rel/@rev in RDFa 1.1 Core? (Maybe an editorial issue; Re: Editor's Drafts Updated)

There is a remark right before Section 6.6, which says:

"There is one exception to this; @rel, @rev, @datatype, and @property can also take as a value any term from the list of terms or from the current default vocabulary."

I am not sure I understand this remark. First of all, @typeof should be listed there, too. But, to my understanding, in this new world, there should be no difference between the behaviour of @about/@resource and the rest, ie, term definitions should also be valid for those. Did I miss some discussions on that?
