NEW ISSUE: How to determine the value of the [destination] property from WSDL?

During last week's concall I took an action to raise an issue regd the 
determination of the value of the [destination] property by looking at 
the WSDL description. Here it is:

* Title - How to determine the value of the [destination] property from 
WSDL?

* Description -
The WSDL binding spec does not define how to determine the value of the 
[destination] property when sending messages to a Web service described 
in WSDL (and when WS-Addressing is also being used for that Web service).

* Justification -
The WSDL binding spec [1] says: "Web Services Addressing 1.0 - WSDL 
Binding (this document) defines how the abstract properties defined in 
Web Services Addressing 1.0 - Core are described using WSDL."
The [destination] property is required when using WS-Addressing [2], but 
the WSDL binding spec does not define how this abstract property is 
described using WSDL.

* Target -
WSDL Binding

* Proposals -

Here are five proposals to resolve this issue:

1) In the absence of additional information, the value of the 
destination property is the same as the value of the 
wsdl20:endpoint/@address attribute in case of WSDL 2.0 or the value of 
{http:address|soapbind:address}/@location attribute in case of WSDL 1.1.

2) Modify the proposal at [3] (for issue i021) as follows:
i) allow the element wsaw:UsingAddressing to be a child element of 
wsdl20:endpoint/wsdl11:port
ii) create an optional attribute wsaw:UsingAddressing/@destination of 
type xs:anyURI. The value of this attribute, if present, specifies the 
value of the [destination] property.

3) Same as (2) but default to the proposal in (1) above.

4) Allow the wsa:EndpointReference element to be included as the child 
element of wsdl20:endpoint or the child element of wsdl11:port. When 
using the wsa:EndpointReference in an wsdl20:endpoint/wsdl11:port the 
usual WS-Addressing/binding rules apply.

5) Same as (4) but default to the proposal in (1) above.
