Jon,

On the other hand, it declares a statement of intended design constraint
(being sip oriented) but provides no indication of what that means or
why it is being chosen. As such, it is not possible to evaluate that
choice.
Given that a working group charter is a contract for work to be done,
the contract needs to specify its constraints in a way that provides
helpful detail.
I think that's reasonable, yes. 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. If there is a body of prior work, on
which this working group is being offered as a continuation, then a
person reading the charter needs to be able to review that work.
Yes, this is also reasonable. 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.
