Subject: RE: [wsbpel] Issue - 280 - proposal draft for discussion

I don't like the idea of mandatory schema validation for the keepSrcElement
case. I don't recall any other part of the spec where we require validation
unless it is explicitly indicated with the <assign>'s validate attribute or
the <validate> activity. Section 8.4.3 describes type compatibility but only
with respect to assigning to and from message variables. I can see how the
keepSrcElement validation could be interpreted as being in the same spirit
as the message variable type compatibility checks but if that's the case
then would people wonder why we don't enforce any other type compatibility
during assigns? 

The proposed changes to the fault matching rules in Section 12.5 look good.
My previous concerns regarding the determination of the fault data type have
been addressed. 

One thing I found missing was that the matching priority only considers the
order of the <catch> elements when there are multiple compatible matches. I
was expecting to see some consideration of the SG hierarchy.

For example:

Given the following SG hierarchy:


...and the following fault handlers:

   <catch faultElement="E1"> ... </catch>
   <catch faultElement="E2"> ... </catch>

If the runtime data is E4 then E1 and E2 are both compatible but E1 would be
selected since it appears first. I would have thought that E2 would have
been selected since it is closer in the SG hierarchy to E4.

Hi all,

Last week, Dieter, Thomas and I have worked together to provide a new 
proposal draft for Issue 280.

Please take a look!
(Since this draft is sent out to the public less than 12 hrs before the 
conf call, I guess voting will be up for in the conf call next week)
