[Doxygen-develop] Generate UML XML?

[Bill Z. <bil...@gm...>]

I'm looking into the use of doxygen to generate an XML representation of
my team's public APIs (C and C++ only), specifically based on (a version
of) the UML DTD.

That way, in theory, I could use doxygen to generate a UML-ized library
of public APIs that I could then import into a UML modelling tool for
re-use in future designs.

If I had the right UML modelling tool, I might just be better off using
it to generate the UML components from the source, but I'd like to
explore whether I could do this with doxygen (or if it already exists),
since my team already uses doxygen to generate HTML documentation.

So, a few questions...

- firstly, obviously, does this capability already exist... i.e. the
  capability to use doxygen to generate UML XML output of my public
  classes & APIs?

- assuming this capability doesn't exist, I think I would have to write
  an app that generates UML XML from the XML that doxygen generates now,
  which makes me ask...

  - what schema does doxygen use by default when generating the
    intermediate XML files?

  - can someone explain the purpose of the XML_DTD config
    parameter... if I use this, does doxygen try to match the XML output
    to the schema defined in the DTD (I assume not)

Thanks, Bill...
