[gme-users] .xme attribute generation

[Jeff Parsons]

Hi,

Okay, I see about the mga versioning - the API shields it.
Interesting suggestion, but there are a couple of other
issues. One is that Xerces, the XML generator I'm using,
is not at all hard to use, so a simpler API is not a big
attraction per se. The other is that the translator design
as it is now will work on *NIX platforms. Giving that up
and going with COM wouldn't be a big deal to me, but it
might to the sponsor and to other folks I work with.

That said, I'll consult with the others involved with
this project and get some feedback before I go any 
farther down the xme path.

thanks,

Jeff
