Dear Jonathan,

your comments on SAWSDL were accepted as our LC issue 1 [1] as
editorial. We believe we have fixed your issues in our current 
draft [2], and the following is a list of our WSDL files that the
WS-Description WG might consider for the test suite.

1. CheckAvailabilityRequestService
http://www.w3.org/2002/ws/sawsdl/spec/examples/wsdl/CheckAvailabilityRequestService

2. Annotated CheckAvailabilityRequestService
http://www.w3.org/2002/ws/sawsdl/spec/examples/wsdl/SemannCheckAvailabilityRequestService

3. CheckInventoryService
http://www.w3.org/2002/ws/sawsdl/spec/examples/wsdl/CheckInventoryService

4. Annotated CheckIntentoryService
http://www.w3.org/2002/ws/sawsdl/spec/examples/wsdl/SemannCheckInventoryService

5. Annotated CheckInventoryService (version 2)
http://www.w3.org/2002/ws/sawsdl/spec/examples/wsdl/SemannCheckInventoryService2
 
6. PartNumber2SKULookupService
http://www.w3.org/2002/ws/sawsdl/spec/examples/wsdl/PartNumber2SKULookupService

7. SKU2UPCLookupService
http://www.w3.org/2002/ws/sawsdl/spec/examples/wsdl/SKU2UPCLookupService

8. PurchaseOrderService
http://www.w3.org/2002/ws/sawsdl/spec/examples/wsdl/PurchaseOrderService

9. MyPurchaseOrder
http://www.w3.org/2002/ws/sawsdl/spec/examples/wsdl/MyPurchaseOrder

I'm not quite sure if our editors have validated these WSDL documents,
I'd expect that to happen at most in our CR phase, which we expect to
enter this month.

Please let us know by Jan 15 if you disagree with our disposition of
your comments.

Best regards and thanks for the comments,
Jacek Kopecky
