Yeah, there's a couple dialects of D-Bus introspection XML and I'm
already aware of most of these (the Telepathy one and the one used by
ConsoleKit/DeviceKit-*  at least). I guess I should have mentioned
Anyway, this effort is mostly about standardizing this stuff and move to
having an common official language that is easier to edit / grasp and
also share among projects (e.g. shared IDL repo). And also to have a
reference implementation of the IDL compiler. It should be trivial to
use the reference IDL compiler to generate the aforementioned D-Bus
introspection XMl variants (at least as an interim step).
Also, one obvious use of the reference IDL compiler would be to generate
nice docs for the D-Bus interfaces that we share via freedesktop.org.
Right now, it's XML and that's a bit frightening...
