Question: why empty introspeciton files from org.freedesktop.Notifications and the like ? Repository of org.freedesktop introspection files available ?

Using the openmoko introspection file and using e.g. the method
org.freedesktop.Notifications.GetServerInformation() yields an
org.freedesktop.DBus.Error.UnknownMethod on Ubuntu.

So it is probable that supplying an introspection file without
interfaces is intentional, because e.g. that service is deprecated (?),
but still important to be available or that its internals got changed,
but the public should not know of it, or ... ?

(There are no means to communicate version or deprecation information
via the introspection file.)

Still, is there a place where the official org.freedesktop introspection
files can be downloaded?
