I have additional questions regarding the license of htmlmathml-f.ent. 
The W3C license is fine in order to ship the file in Mozilla. However, 
there is a problem with the following clause, which only allows to copy 
the entity names:

"Some entity names in this file are derived from files carrying the
  following notices:

      (C) International Organization for Standardization 1986,1991
      Permission to copy in any form is granted for use with
      conforming SGML systems and applications as defined in
      ISO 8879, provided this notice is included in all copies."

Does the expression "entity names" refer to the name in comments (so 
that removing the comments would allow to make the file compatible with 
Mozilla's requirement)?
Isn't this paragraph contradictory with the W3C license, which does 
allow modifications of the file?
Also, I believed that the file was generated from unicode.xml, which 
only mentions the W3C license...
