Hi,

We are currently in AUTH48 for draft-ietf-avtcore-rfc5285bis which 
references Bundle and SDP-Mux as it defines the mux category for its SDP 
attributes. As we made some last minute changes to MUX catergory for the 
extmap-allowed-mixed attribute we found some text needing changes. This 
anyway resulted in us noticing a missmatch between BUNDLE and sdp-mux.

So Bundle (-39) states:

8.1. Mux Category Considerations

    When an offerer or answerer associates SDP attributes with a bundled
    "m=" line (including any bundle-only "m=" line) associated with a
    shared address, IDENTICAL and TRANSPORT mux category SDP attributes
    [I-D.ietf-mmusic-sdp-mux-attributes] are associated with the "m="
    line only if the "m=" line is also associated with the offerer/
    answerer BUNDLE-tag.  Otherwise the offerer/answerer MUST NOT
    associate such SDP attributes with the "m=" line.  The rule above
    does not apply to a bundled "m=" line associated with a unique
    address.


However, SDP-mux states:

4.3. Category: IDENTICAL

    The attributes and their associated values (if any) in the IDENTICAL
    category MUST be repeated across all the media descriptions under
    multiplexing.

To my understanding the first is correct, but the change in BUNDLE has not been
reflected into SDP-mux doc. I assume that is in part due to its approved status.
Has the authors tracked the set of changes that are needed due to changes in BUNDLE?

Do there exist a text change for this missmatch?


Cheers
