I worry about the implementation burden here.  Jos, and other
implementors of OWL Full consistency checkers: do you plan to
implement support for XML Literal?  I'm not clear anymore what work is
really entailed here.  I heard on the call that c14n equivalence was
no longer needed, but that well-formedness-checking was.

I'd think another test should be added which is "Full" only and has
the opposite conclusion.

It does seem odd, but I like it a lot.    Except maybe we can ask the
F-OWL folks [1] what they have in mind.
