[MMUSIC] Comments on draft-ietf-mmusic-sdp-srcfilter-01.txt

[Magnus Westerlund <magnus.westerlund@era.ericsson.se>]

Hi,

I have some comments about the draft.

Section 2 and Appendix A.
The definition of the filter attribute. Wouldn't it be better to define 
a short attribute name to the source filter instead of having two 
attributes called incl and excl? I would propose 
a=SF:<filter-mode>:<filter-spec>.

Section 2.2.
The media description 1 port number is not even, Please change to 54320 
which is a possible number. Also the payload type for video shoul be 
changed. A possible value would be 34 that are a static payload type for 
h.263 video.

Section 2.2.4
The example text is in contradiction with the processing rules in 
section 2.1. According to the processing rules all three src adresses 
(1.1.1.1, 2.2.2.2 and 3.3.3.3) are valid for any of the three multicast 
adresses.

Appendix A.

The definition of src-list i believe is in error. The addresses should 
not be seperate by email-safe but rather SP.

The definition from draft-ietf-mmusic-sdp-new-10.txt says:
email-safe =          1*(%x01-09/%x0B-0C/%x0E-27/
                         %x2A-3B/%x3D/%x3E-FF)
                      ;any byte except NUL, CR, LF, or the quoting
                      ;characters ()<>

Which includes lots of more charachters than space which is referenced 
in the text in section 2.

Regards
