  b) is a bit extreme, and should probably be fixed *but* any XML 
passed though an HTML parser loose all its garantee of portability
that drove to use XML in the first place, this is broken. island
of foreign vocabularies in XHTML makes sense, but not in SGML HTML.
  Add a request for enhancement about not converting the names
to lower case in bugzilla, that could be added as an HTML parsing option
and probably not too hard to add.
