The MathML people are very keen on entity references.  I think they want
the complete set of ISO entities + their own ones.  MathML seems to use 
almost all the standard ISO entity sets: I cannot see isogrk1 or isogrk2 
(they are used for written Greek).  The list is below, taken from
http://www.w3.org/TR/MathML2/appendixa.html#parsing_dtd

Perhaps we need a "standard entity set profile":

   1) XML 1.0 built-in named entities 
   2) HTML's collection (isolat1, isopub, including Euro) 
   3) MathML's large collection 

with the following recommendation:
  i) Document types used for data-transfer between machines should use 1)
 ii) Document types used for simple business applications should use 2)
iii) Document types for publishing, or based on XHTML, should use 3)

That helps each of the three main uses: data transfer,  small documents and 
high-end publishing.

Cheers

P.S. I don't like the &thai_character_ko_kai;. much.
