I took an action item to make a proposal for the syntax of attributes in 

I've *started* on it, and have enough that I would like to get some 
feedback before going further.

Attached is a snippet from section 6 of 4566bis (SDP Attributes) to 
which I have added some ABNF syntax for just the values. (Each addition 
starts with "Syntax:")

This isn't necessarily the *form* it will take when done. For now what 
I'm looking for is feedback on the substance.

Of particular concern - when the format has text values, should those be 
case-sensitive (the default for SDP), or case-insensitive? I think we 
need to sort this out by what the common usage is.
