I'm just tracking the unicode.xml file, as opposed to referring to the TR, 
so publication actually won't affect HTML5. :-)

I've sent a request to the XHTML2 group on the matter:

   http://lists.w3.org/Archives/Public/public-xhtml2/2008Apr/0022.html

Personally I'd rather the file was under one person's exclusive ownership, 
guided by feedback from everyone else, rather than under some sort of 
committee control where getting anything changed requires agreement from 
fifteen people instead of one person coordinating everyone's wishes 
asynchronously. But it's not up to me. :-)

Agreed.


I've changed my script so that it takes all the sets listed under "html5" 
and "mathml". This removed the entities that were only in the following 
groups:

  8879-isoamsa, 8879-isoamsb, 8879-isoamsc, 8879-isoamsn,
  8879-isoamso, 8879-isoamsr, 8879-isobox, 8879-isocyr1, 8879-isocyr2,
  8879-isodia, 8879-isogrk1, 8879-isogrk2, 8879-isogrk3, 8879-isogrk4,
  8879-isolat1, 8879-isolat2, 8879-isonum, 8879-isopub, 8879-isotech,
  9573-1991-isoamsa, 9573-1991-isoamsb, 9573-1991-isoamsc,
  9573-1991-isoamsn, 9573-1991-isoamso, 9573-1991-isoamsr,
  9573-1991-isogrk3, 9573-1991-isogrk4, 9573-1991-isomfrk,
  9573-1991-isomopf, 9573-1991-isomscr, 9573-1991-isotech,
  9573-2003-isogrk1, 9573-2003-isogrk2, 9573-2003-isogrk4,
  ISOlat2,
  predefined

Could you add "predefined" to the list of html5 sets? While it's redundant 
with the xhtml1+mathml sets, I'd rather it was there explicitly since that 
more accurate represents the intent (we added &apos; to HTML5 so that XML 
entities would work in text/html).
