Re: [MMUSIC] 1 week WGLC on recent changes to draft-ietf-mmusic-dtls-sdp (-14 to -16)

Hi,

Below are comments that my colleague Nevenka provided (she has subscribed
to the list, but hasn¹t been accepted yet). I¹ll address them in a
separate reply.

Hello,

 
I reviewed draft-ietf-mmusic-dtls-sdp-16.txt and have the following
comments:

 
-         In Section 1 the following statement is not aligned with the
recent change which made "dtls-id" attribute globally unique i.e. the pair
of "dtls-id" attribute values (the attribute values of the offerer and the
answerer) uniquely identifies the DTLS association instead of the
"dtls-id" attribute pair in combination with "fingerprint" attribute
values (the attribute values of the offerer and the answerer). Thus the
following sentence requires modification:

"The ¹dtls-id¹ attribute pair in combination with ¹fingerprint¹ attribute
values from offer and answer SDP uniquely identifies the DTLS association."


-        In section 4 there are contradicting statements related to a
default value of "dtls-id" attribute:
"Default Value: empty value "
 
But the text says:
"No default value is defined for the SDP ¹dtls-id¹ attribute. "
 

Based on the above text  "empty value" should be replaced with "N/A²


 
-        I believe that RFC 4572 should be included in 14.2 since it is
(and should be) referenced in sections 9.2 & 9.3 from old text in RFC 5763
and RFC 7345, but the new text requires modification and should refer to
draft ietf-mmusic-4572-update (but currently still has reference to RFC
4572).


 
-        In addition I also found some editorial nits that I have provided
directly to the authors.
 

Kind regards,

Nevenka
