Given that neither of HTML 5 nor XHTML 5 require rel values to be lowercased, I
can't see why the polyglot spec (which aims to help authors write documents
that conform to both) should require it.

i.e. rel="FRIEND" and rel="friend" are considered equivalent under HTML 5 and
XHTML 5.

A generalised XML processor with no special knowledge of XHTML will have
problems of course, but merely lowercasing the attribute won't help such a
processor. Consider rel="friend met" versus rel="met friend" which are
equivalent under HTML and XHTML rules, but a generalised XML processor won't
treat as equivalent.

Note also that this bug should also cover rev.
