Hi Dieter,

-1 to the proposal.

Copied from the word doc:
======================

- paragraph after the fault catching rules, from:

Matching the type of a faultVariable to fault data as mentioned in points #1 and #4 above is more restrictive than in points #2 and #5. A WSDL message type variable can only match a WSDL message type fault data, while an element variable can only match element based fault data. They match only when their QNames are identical.
 

to:
 

Matching the declared type of a faultVariable to the declared type of the fault data as mentioned in points #1 and #4 above is based on QName matching of the declared variable types. This means, if a variable declared with element type tns:bar is thrown, a catch with faultElement="tns:bar" will catch it.
======================

As mentioned before, this proposal essentially create a psuedo-data-model in BPEL which treat type always *static*.

This static psudo-data-model significantly contradicts:

• *Any* data typing language that supports inheritance and polymorphism including:
• e.g.: XML Schema: "extends" and "xsi:type" feature
  
  
• XPath 2.0 / XQuery 1.0 data model: where the type is dynamic, not static
• See "treat as" and "cast as" operations:
  http://www.w3.org/TR/xpath20/#id-cast
  http://www.w3.org/TR/xpath20/#id-treat

The not-well-founded urge to quest for skin-deep-level symmetry in <catch> will abrupt the future adoption of other standards.

I would prefer Mark Ford's original proposal.

Thank you!



Regards,
Alex Yiu
