ice-sip-sdp update

[juberti]

Ensure that ice-sip-sdp (S 4.1) has been updated to allow FQDN addresses.

What are the next steps here?

ice-sip-sdp sayeth:

  <connection-address>:  is taken from RFC 4566 [RFC4566].  It is the
  IP address of the candidate, allowing for IPv4 addresses, IPv6
  addresses, and fully qualified domain names (FQDNs).  When parsing
  this field, an agent can differentiate an IPv4 address and an IPv6
  address by presence of a colon in its value - the presence of a
  colon indicates IPv6.  An agent generating local candidates MUST
  NOT use FQDN addresses.  An agent processing remote candidates
  MUST ignore candidate lines that include candidates with FQDN or
  IP address versions that are not supported or recognized.  **The
  procedures for generation and handling of FQDN candidates, as well
  as, how agents indicate support for such procedures, need to be
  specified in an extension specification.**

Perhaps this spec should explicitly update mmusic-sip-sdp as providing a procedure for handling mDNS FQDN candidates. Probably something for the WG to weigh in on.

The latest guideline from the email thread is to update ICE-SIP-SDP in the mdns-ice-candidates draft.
