Hopefully the document citations you counsel us (below) to include would help with this to some degree. I also think importing some high-level text to the charter making a few of the more important points (i.e. the need to identify media security solutions that can interoperate with application-layer conference administration) would also probably be appropriate. > > PJ> As to why this proposed WG is more or less SIP-specific, the charter arises > PJ> from a set of framework, requirements and mechanism documents that were > PJ> proposed in SIPPING. > > Working groups that are chartered with documented constraints are > expected to cite those documents.

The XCON BoF charter cited five SIPPING documents (largely of a framework/requirements bent), and seven contributions that were believed to be applicable to XCON itself, but those documents were not carried over to the proposed XCON WG charter. I think it would make sense for at least some of these documents to be included in the WG charter as well. > Otherwise it is very difficult for a public review of the charter to be > based on anything substantial. > > If there is no documentation for the constraints, then there is no > substantial basis for imposing them, other than perhaps citing some > concerns or perspectives. > Thanks, this was very helpful.
