Below is my proposed spec text for Issue
218 for your review. Please provide me any feedback that you may have:
Proposed Spec Text Changes to resolve
Issue 218
In Section 12.6, after paragraph 1:
Add:
“The same isolation semantics apply to
properties, being merely projections of variables and thus always coupled
with them; access to properties is identical to access to variables, which
is controlled by the enclosing isolated scope.”
In Section 12.6, after paragraph 3:
Add: “Any partnerLinks declared within an
isolated scope have their access protected by that enclosing scope; the
protection applies specifically to the endpointReference part, and not
the messageExchange parts, of the partnerLink state. Any messageExchange
declared in a scope serves only to provide a handle to access a facet of
the state of its associated partnerLink; it is intrinsically stateless.
The control afforded by the enclosing isolated scope does not apply to
messageExchange handles. Rather, partnerLink states are protected based
on the endpointReference.”
“By definition, correlation sets are only
mutable at initialization; they are immutable throughout the remainder
of their lifecycle. Any correlation sets declared within an isolated scope
do not have their access controlled by the enclosing scope. However, the
initialization of a correlation set declared within an isolated scope is
performed in an atomic fashion – in the same sense as that of an <assign>
operation – ensuring that the correlation set will not be initialized
partially or wholly by multiple concurrent inbound message activities.”
