Re: [siprec] Can an MS object span several CSs in a CSG?

["Charles Eckel (eckelcu)" <[e-mail]>]

Hi Ram,

I think that is many cases, they will be treated as separate MSs due to
the complexities you mention. However, I am trying to understand if
Partha feels allowing an SRC to treat them as a single MS is still
required. If not, then what is a use case? A concrete example would help
me, and potentially others, to better understand the motivation behind
Partha's requirement for modeling media from multiple CSs as a single
MS.

Cheers,
Charles
