I think that I will do this for now.  I also need to add a new
element anyway for other purposes so I'm going to stray from docbook
slightly in the mean time.  I'll probably add my own versions of
the equation tags so as not to polute the original meaning.

So, back to my original question.  Can you help me with the scheme/DSSSL
that I would need to transform some SGML into a different bit of SGML
before passing it on to the rest of the stylesheets?

Imagine that I define a new element, <xequation> some tex equation </xequat=
ion>.
Is it possible to use DSSSL to rewrite this as:
<inlineequation> <graphic fileref=3D"foo"> </graphic> </inlineequation>
and have the rest of the stylesheets process the inlineequation in
the normal way?

I haven't got my head around DSSSL enough yet to know whether this is
possible or not.
