     * modules can group their internal AVPs under a xavp, so other xavps with same name in global list won't affect the module functionality. Say dispatcher groups its avps under "dispatcher". Inside that list it can have xavp with names: dst, grp, cnt. In the global list or other sublists can be other avps with name 'dst', without any interference.     * modules can group their internal AVPs under a xavp, so other xavps with same name in global list won't affect the module functionality.

 +    * **dispatcher** module can reserve xavp name "dispatcher" via modparam, while the names for AVPs dst, cnt, grp can be predefined and documented in readme.
