Hi Cullen:

I am writing as an author of this draft.

This draft has been hanging around for years, and it was always presented 
as a collection of small capabilities that could be used independently, 
but, due to similarities, and in order to avoid the explosion of 
internet-drafts, could be documented together.

At IETF 73 the draft was already presented indicating that "This new 
draft collects these miscellaneous capabilities into a single document." 
You can check the slide #3 at:
http://www.ietf.org/proceedings/73/slides/mmusic-6.pdf

At that point in time, while there were questions about the intention of 
the various capabilities defined in the document, none raised the 
question of the documentation of these capabilities in the same document. 
I don't recall anyone having a problem because we were specifying three 
independent capabilities in the same document.

At some point in time, I consulted 3GPP, because I knew this draft was a 
dependency, and I was told that 3GPP was only using one of the 
capabilities, but was OK with documenting the other two in the same draft.

If we apply the same logic to most of our documents, we will need to 
revise other drafts that we are specifying and we should trim 
capabilities or attributes that are somehow independent of the others. I 
think this is a tedious task at this stage.

I therefore propose to continue with the existing document as is.

BR,

      Miguel

Clearly this is not a huge technical issues but a small procedural thing so I leave it up to the chairs what they want to do.
