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

Hello Albrecht,

OK I see your point, the usage of "recursion" doesn't meet 
mathematical/logic definition. I'm OK to rename it. Maybe the "multiple 
value response" wildcard?

With regards to AVD-4504 I think i'd be happier adding "~" if we also 
tied that capability to a package.

Regards, Christian
