It's a funny story.  In earlier versions of Unicode, SARA AM was treated
as canonically equivalent to NIKHAHIT followed by SARA AA; that is,
Unicode-conformant processes were not supposed to distinguish between
them.  In the latest version, this equivalence has been downgraded to
a mere compatibility equivalence.  As a result, SARA AM has become
a "compatibility character" and as such disallowed by the Appendix B rules.

> > 0EB3;LAO VOWEL SIGN AM

The same story applies here: the VOWEL SIGN AM is now a compatibility
equivalent of NIGGAHITA followed by VOWEL SIGN AA.

In any event, whatever XML worked before has to work now, so I am merely
proposing a statement that THAI CHARACTER SARA AM and LAO VOWEL SIGN
AM *are* legal in XML names, despite their status as Unicode compatibility
characters.  In any case their legality in XML *text* is of course not affected.

If anyone thinks something is desperately broken here, please contact
unicode@u... right away.
