Well, you cut off the citation too soon.  I am talking about
character treatment only, and in
<message:[log in to unmask]> I write "the program
-- or XML file format -- must provide a way to mark math areas, and
it must apply rules or whatever to typeset accordingly."

So you distuguish between both cases within your Gellmu tools?
Okay, we have to, I do so, too; but actually I think that this is
something that the typesetter should provide.  So, an \alpha in math
mode should be cmmi, and in text mode is must be part of a Greek
