There's lots of stuff which is, ahem, fragile, in particular
the XML output stuff.

Well, it seems current XML supportis more for debugging purposes,
but adding some more serious support for reading and writing will
certainly be a worthwile addition. Instead of the homegrown format
a somewhat more widely used vocabulary would seem in order, however,
there are quite a few XML vocabularies for generic graphs out there,
but not really anything a standard blessed by some acknowledged
consortium nor a sort of "industry standard".
Some Candidates for discussion:

A XML-ification of the GraphViz input would be also worth a look,
if anybody is interesting in graph layout.

Any takers for writing up a comprehensive review of these formats?
