Introspect method call

[Gaurav Roy]

What has to be done at the server object side to have a working version 
of the following call?

dbus-send --system --type=method_call --print-reply --dest=[service] 
[object_path] org.freedesktop.DBus.Introspectable.Introspect

Have seen for most DBUS objects of various types it works.
However for one particular object it returns blank XML instead of method 
call descriptions, though the server is reactive to the method calls.
Do only DBUS-GLIB ised server side codes support this method call? Can 
some insight be provided as to how the Introspect call works?
