I'm not fully aware of UML and XMI. I understand that the OMG (?) provided
an XML serialization format for UML. Assuming it is XML, then I would expect
it to be based on a standard DTD, and possibly extra type constraints
added to the XML content.
In that case this really mean that the XMI support can be designed as a
library based on top of libxml. I would then suggest to keep the source
base somewhat separate but check that you use as much as possible stable
APIs for libxml entry point to minimize the potentiality of conflicts
as libxml evolves. the point is that libxml already has a tendency to grow
a bit too much as I add features. So I encourage your effort, but I'm
not 100% sure it really make sense to add XMI directly (unless I didn't
really understood what XMI was intended for).
It could be a good idea to check with Dia author too, integrating such
a library directly or at least reusing it in DIA would certainly make
sense too since well is targetted specifically at UML.
Sounds reasonable ?
Daniel
