Nope.  Fetching the MathML DTD + modules by HTTP is too big an overhead
and will slow the server unacceptably.  We need to keep local copies,
which means we're stuffed if you change the DTDs by stealth (i.e. without
creating a new public identifier for the updated DTDs).

It would be more helpful if you could notify us whenever the DTDs are

I guess the basic problem is we never expected DTDs to change without
it showing in their PUBLIC and SYSTEM IDs, so we're not geared up for
automatic mirroring.  I'm wondering what would be the implication of
setting up a cron job to fetch the whole lot weekly or something?
