Technical Summary
 
This document defines a new security precondition for the Session  
Description Protocol precondition framework described in RFCs 3312  
and 4032.  A security precondition can be used to delay session  
establishment or modification until media stream security has been  
negotiated successfully.
 
Working Group Summary
 
This is a typical application of the SIP/SDP preconditions framework.  
There was no controversy surrounding the work, and it is needed by a  
range of SIP users.
 
Protocol Quality
