Re: [wsbpel] Issue - 32 - Link Semantics in Event Handlers

Chunbo, Edwin

According to a messge from Satish, 
http://lists.oasis-open.org/archives/wsbpel/200305/msg00131.html
Edwin's view seems to be closer to the original authors' intention.

The problem is that the specification itself allows at least two
interpretations. I raised this issue to clarify which is the right one.
After the discussion and the issue/requirementprocess mature, 
I probably propose a motion to pick one iterpretation.
