Re: [bfcpbis] I-D Action: draft-ietf-bfcpbis-rfc4583bis-03.txt

I'm not sure we should say much about this in rfc4583bis. This is 
similar to existing "best effort encryption" schemes, where different 
vendors historically have had their own interpretation of a best current 
practice.

Anyway, it is not a big deal adding an informational note, if people 
thinks that's a good idea, explaining that one may very well meet an 
mstrm referring to a still undefined label.

(Do we then reference the IMTC document as an informational reference or 
simply state the fact that this behaviour exists in the wild?!)

(The intention is that if the SDP answer indicates that the peer understands both BFCP and the SDP content attribute, a re-INVITE can be sent adding an additional BFCP-controlled video stream with "content:slides".)
