IMHO it should only be a wf-requirement to check for name characters
only with a granularity of  the low half-blocks: an application should
only need to look at 512 notional bits to test well-formedness of names,
apart from the first half block (i.e., the ASCII repertoire).   XML will
track Unicode, so the fine-grained approach of allocating name roles
character-by-character to every Unicode codepoint is overkill for
well-formedness and perhaps even for validity.

The full rules can be kept for full validity or as guidelines for
generating data. They are not bad, they are just more than is needed.
