Title: [sca-bpel] Issue 61: proposal

As I was discussing on the call, I'd like to suggest changing the
following sentence:

"SCA BPEL In an SCA WS-BPEL Runtime,
variables associated with SCA properties and

multi-valued reference references are set by
the runtime based on the configuration

of the containing composite. "

I have to check, but on last week's call, Mike was saying that Assembly
has a defined term (along the lines of "Domain Configuration"?), which
I think should be explicitly referenced instead of  the phrase "based
on the configuration of the containing composite."  I think that the
current wording is too loose, and confusing.

At the end of section 3.1 Properties we add the
following text:

  

The WS-BPEL specification requires that the variable initialization

logic in scopes that contain (or whose children contain) a start

activity use only idempotent functions in the from-spec. In an SCA

WS-BPEL Runtime, variables associated with SCA properties and

multi-valued reference are set by the runtime based on the configuration

of the containing composite. Therefore, the idempotency is guaranteed

only for a given SCA domain-level composite. The SCA Assembly

specification allows for a variety of implementation including ones that

allow dynamicity for the SCA domain-level composite. See Sections

10.7.1, 10.7.2, 10.8 and 10.9. For such runtimes, the properties and

muti-valued references may change with a change in the domain-level

composite.
