Hi,
I read the draft, some comments:

1. I think it needs an offer answer section. We need to specify the behavior
when an offer to encrypt the header is sent and the answerer do not support
the encryption header extension. Can alternatives, one with encryption and
one without be offered. 

2. Extmap can be a session level attribute. What about encryption, is it
only a media level.

In general are the offer answer rules from RFC 5285 applicable here and how.


Regards
Roni Even
