hi Ian,
i agree that this consistency is critical.  But how much WSRF or
ws-trans/ws-enum must be visible to the application builder?  Perhaps
it is essential that one or the other must be exposed.  i don't know.
perhaps doing so just adds another layer abstraction layer as frank
suggests. but it may also be that we have defined the wrong abstraction
layers to start from.  again, i don't know.

my other point is this: i don't see this as a debate with MS.  i see a
debate right in the core of GGF membership.  from what i can see, MS is a
no-show at this party.
