The authors have improved much of the description, and cleaned up a few technical issues, so please review carefully.

For the XML - Lorenzo has validated the XML schemas using Eclipse and XML Spy. If you validate against a different validator, it would be helpful if you let me/Eric know, because this will be a question that we answer in the shepherd writeup.

>    The MediaCtrl work group in the IETF has proposed an architecture for
>    controlling media services.  The Session Initiation Protocol (SIP) is
>    used as the signalling protocol which provides many inherent
>    capabilities for message routing.  In addition to such signalling
>    properties, a need exists for intelligent, application level media
>    service selection based on non-static signalling properties.  This is
>    especially true when considered in conjunction with deployment
>    architectures that include 1:M and M:N combinations of Application
>    Servers and Media Servers.  This document introduces a Media Resource
>    Broker (MRB) entity which manages the availability of Media Servers
>    and the media resource demands of Application Servers.  The document
>    includes potential deployment options for an MRB and appropriate
>    interfaces to Application Servers and Media Servers.
