I completely agree that our use cases
should be BP 1.0 compliant – in fact I would vote to mandate that.

As I hinted in my previous
note, I do not feel that strongly about point 4. It would be fine with me if it
is only a recommendation instead of a requirement.
I would still be very much in favor
of our Use Cases WSDL artifacts to be compliant with BP 1.0.

I guess I am not seeing why we need to
take on this problem – RPC encoded or literal does not matter to the BPEL
process. If someone is policing WSDL 1.1 usage let them enforce that.
We can recommend BP 1.0 compliance for interop but if BPEL is used in
environments where BP 1.0 is not feasible or needed, what does it mean for us
to forbid the usage?

Right, RPC literal would be fine,
but RPC encoded would be in violation.

So for instance the RPC encoded services
bound to SOAP/HTTP would be in the “in scope but in violation”
category?

Let me clarify point 4 (sorry, I
mislabeled it as 3) in relation to point 1.
I think we should distinguish
services that are not compliant with BP 1.0 from those that are simply out of
scope for BP 1.0.
If I have a Web service that is not
bound to SOAP/HTTP, then I would say it is out of scope for BP 1.0, so it's OK
for BPEL to interact with it.
My point 4 is about services that
are within the scope of BP 1.0 and still do not comply with its requirements.

I doubt that we can mandate BPEL to be
used with BP 1.0 compliant services only especially given the answer to 1
assuming it is correct, and given that there are many services today that are
not compliant (e.g., RPC encoded ones).

I see a few separate
issues/questions connected to the relationship of BP 1.0 and BPEL.
1- Would BP 1.0 be restricting
BPEL to the point that some of BPEL's functionality would not be available?
I cannot think of any such
restriction off the top of my head.
2- Would the fact that BP 1.0 only
addresses the SOAP/HTTP binding imply that also BPEL should be limited to that
type of binding?
I don't think that anybody would
imply that.
3- Should a BPEL process be offered
as a Web service that is BP 1.0 compliant?
My answer would be yes.
3- Would it be fair to limit BPEL
use to interacting with BP 1.0 compliant Web services only?
My personal answer would be yes. But
I am a member of WS-I, and I understand other people might have different
answers.

For the benefit of the non-expert could
post a salient example please? Specifically, a BPEL usage pattern that
would not work if BP 1.0 is followed but would work if any WSDL 1.1 portType is
allowed. In other words, is BP 1.0 a restriction on the WSDL artifacts we
use or potentially on BPEL itself?

The sections 5.5 and 5.6
in the basic profile (http://www.ws-i.org/Profiles/Basic/2003-08/BasicProfile-1.0a.htm)
are devoted to binding aspects but, several major sections including section 4,
other sections of 5 address abstract aspects of WSDL, which is a pretty large
portion. All those are applicable BPEL IMO.

Most of the BP 1.0 directives are binding

Can someone identify a directive in BP 1.0 that actually affects BPEL?
