Start with H.248.1v3/clause 6.2. That should give you some idea of how 
to construct the syntax. Details for the MUX descriptor are given in 
clause 7.1.3. I can put the whole picture together for you if you have 
trouble, but I should warn you that my views differ from those published 
as H.248.20.
