For the most part, this is much more succinct way of saying what I was
trying to say.  HTML allows the attributes and if an author uses them,
it should not affect conformance. I only slightly disagree in that
conformance isn't silly in that it is good to know whether or not you
are following the rules when it comes to authoring an RDFa Lite
document.  Maybe we need to clarify that conformance is scoped to
authoring and not to "processing" the document?

The processor must follow the same rules when extracting triples via
RDFa and that is where I don't want to go mucking around and changing
semantics just to preserve some expected behavior.  If you use @rel
and things change, then you may have to adjust your use of RDFa to get
the right outcome.
