	Exactly ! At the A (Architecture) and I(Infrastructure) layer,
we should *only* capture the serviceData (and associated vocabulary) and
the behavior of the service.

	How it is implemented is up to the implementers. But for
interoperability we need the same way of representation - that is where
the WS-xxx proposals come in. They provide interoperable syntax and
semantics at the wire level. BTW, your comparison of sourgeforge project
is not accurate here.

	Going a little deeper, we have the security roadmap based on the
WS-XXX roadmap and a set of Grid specifications listed in the documents.
That is what we are executing against i.e. making the grid roadmap a
reality by gathering wgs around specific deliverables.

	If (actually when) tomorrow a new concept comes out - be an XML
proposal or a binary idea or a way of doing something, we would check it
out and see how it fits in our security architecture. We will update the
architecture document and articulate what artifacts are required. May be
at the I(Infrastructure) level or may be at the A (Architecture) level.
Then we would develop the required artifacts - either as a separate wg
or an existing wg.

	So any bottoms up or top down concepts go thru the same process
- incorporate in the architecture, define artifacts and then develop
them. BTW, when we define in the architecture we might do a subset by
profiles - nothing says we need to consume the idea/concept/proposal
fully.

	On the question of how long to wait is an art. In this case, we
should start ASAP on the Ws-XXX related Grid specifications, as we need
these concepts in the Grid. In that sense the waiting depends on the
concept.
