[Standards] XEP-0176 ICE candidate properties

[Paul Witty]

Working towards an implementation of ICE with Jingle, the definition of 
ufrag and pwd don't seem to match between XEP-0176 and ICE CODE.  ufrag 
and pwd are defined per candidate in the XEP, but seem to be per stream 
in ICE-19.  Section 15.4 says "The "ice-pwd" and "ice-ufrag" attributes 
can appear at either the session-level or media-level."  Should they be 
moved to attributes of the transport or content element describing a 
stream, rather than being specified per candidate?
