[H.248.39] Advanced SDP Wildcarding Package - Recursiveness vs multiplicity

Hello Christian, Tommy,
thanks for the package proposal, a good solution for the related problem in our opinion.

One pre-meeting comment concerning terminology, because possibly caused by us. We were also struggling (when working on AVD-4504) with the editor's note concerning "recursion", but couldn't remember a real example.

If we consider a single SDP line, then recursion would be a structure like "X = Y ... X ...", right?
However, such SDP line grammar is not possible.

If we consider line interlinkage, then a circular definition could be e.g.
X = Y ...
Y = X ...
But again, such SDP line grammars are not possible.

Thus, perhaps we should term the "$R" wildcard as "multiplicity wildcard" or sth similar, but not "recursive wildcard".
Or "cardinality wildcard" ... hm?

What do you think?
Albrecht
