1.  Introduction

   The Conference Event Package [RFC4575] defines means for a SIP User
   Agent (UA) to obtain information about the state of the conference,
   the types of media that are being used, the number and state of
   current participants, additional sources of information such as a web
   page, availability of recordings and others.

   Details describing auxiliary services available for a are included
   within a <service-uris> child element of the <conference-description>
   element.  Such details are presented as a set of <entry> child
   elements each containing the URI allowing access the corresponding
   auxiliary service.  In addition to the URI, entries can also contain
   a descriptive <display-text> element and are expected to also have a
   <purpose> element that specifies their nature as illustrated in the
   following example:

   <conference-description>
   <subject>Agenda: This sprint's goals</subject>
     <service-uris>
       <entry>
         <uri>http://sharepoint/salesgroup/</uri>
         <purpose>web-page</purpose>
       </entry>
     </service-uris>
   </conference-description>

   In addition to the "web-page" purpose mentioned above, [RFC4575] also
   defines several other possible values in a "URI purposes" a sub-
   registry "URI purposes" under the existing registry: http://
   www.iana.org/assignments/sip-parameters.

   This specification adds the "grouptextchat" value in this "URI
   purposes" sub-registry.  The new value allows conference mixers or

   focus agents to advertise a multi-user chat location (i.e.  a chat
   room) associated with the current conference.
