I'm searching for the source of a max length limit on the "a=mid" attribute.

I couldn't find it in RFC 5888 (grouping framework) or RFC 8843 (BUNDLE).

Does anyone remember where it's supposed to be?

(I have code that will insist that it should be 16 bytes or less, but 
I'm trying to verify that this is the correct limit.)
