Throwing the exception is IMHO the most XOMmish behavior; the user is
attempting to do the Wrong Thing and should be stopped.  You don't
silently ignore illegal characters in element names, you except.

IOW, you can't 100% treat a CanonicalXMLSerializer as a Serializer.
Nor can you stuff 10# of *%$@ into a 5# bag.  Life is like that.
