Yeah, I looked through the current generator some more and most of the code
for the PDF export seems to be focused on exporting the data rather than the

I think, however, the generic class structure for the dia xml export would
be similar to he PDF/XML export, as there'd be functions generating headers
and footers as well as functions to handle the different types of objects
(arrows, boxes, etc) and to handle the relative locations/colors of all uml
objects on the grid. Then the function that determines the schema would call
each of these auxiliary functions to put the schema into place.

A similar thing could be done for exporting to svg and eps.

Finally, for organization, would there be some sort of overall class that
handles processing the schema and then have subclasses for each different
format (xml, svg, eps) that takes care of the details of outputting the
schema as a diagram? So the overall class might have functions like
"determine_schema" whereas each subclass would have "draw_arrow", "draw_box"
(which write the xml), etc. Would something like that work?
