Luca,

Yes we should update the errata doc for these entities, as I mentioned
on this list the other day we are presently trying to finalise a DTD
that brings everything in line with the final version of Unicode 3.2
(which has come out since mathml2).

The situation with these (and also the negative spacing characters) is
that it became clear that they were not going to get into Unicode.

<mspace/> was extended (from the mathml 1 version) for this reason, and 
the recommended way to specify a good break is now
<mspace linebreak="goodbreak"/>
see
http://www.w3.org/tr/mathml2/chapter3.html#presm_mspace

Unfortunately some of the older non standard character descriptions got
left in Chapter 6. If they are in the current MathML2 DTD they will be
kept for compatibility reasons (but mapped to Unicode zero width space)
Ones that are not in MathML2 DTD should be removed from Chapter6.

Hopefully we can announce the fixed DTD/character set soon.

David
