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

["Dieter Roller" <ROL@de.ibm.com>]

... this is exactly the point I wanted to make. The semantics for
processing event handlers gets more complicated... And we haven't even
talked about the exact semantics of serialization...

Cheers,

Can we scope this into two separate issues.

1. Serialization of the same event handler.

2. Serialization of separate event handlers in the same scope.
