Thanks - I'll think about this.

I'm not suggesting fixed bindings. I'm suggesting that the document (+its
metadata, environment, packaging, etc.) identify the application to be used
to process it. IOW a MathML document will - in some way - launch a
mathematics-aware application. (It's no use launching DSSSL). And CML will
launch a CML-aware application. Now, if we have a document with both MathML
and CML we need to have a generic processor like JUMBO which can launch the
Java classes for each element. Perhaps this is mainly a software issue,
rather than an architecture one, but we at least have to know where to find
the applications. And XSL would give us the chance to choose different
applications if we wanted.
