Yeah, it's a fairly simple header + tag-length-value list of
attributes format. The RFCs would have worked as a reference too, but
they are numerous, and there are vendor-specific things not described

Don't know, but I suspect it is something internal to them. Maybe
they found it easier and/or safer to transform to/from XML format when
manipulating the data. I am pretty sure there is nothing in DIAMETER
which requires XML.

Sorry, no help here.
