RE: [destination] MAP and WSDL address

We made them dependent in order for the values to be driven by WSDL.
Further, we wanted the destination to always contain a value (unless it
is an anonymous response). The intent was not to prevent the override,
but to require a "value" for the destination to be present unless it is
a synchronous response. The problem is due to mapping destination
property (mandatory) to wsa:To (optional). The wsa:To is optional only
when the destination is anonymous (hence synchronous response). 
The case you are referring to does not pertain to the synchronous
response but to the destination property which is intended for the
request message to be sent. I do not think we deliberately wanted to
prevent the override in this case. That is my recollection anyway.
It seems that we could relax the language to allow the override with
careful wording by requiring the destination to always contain a
meaningful value (i.e. non anonymous) unless it is a response message.

	Subject: [destination] MAP and WSDL address

	The WS-A WSDL spec appears to be too restrictive wrt
[destination] MAP.   
	Here is the text: 
	>> 4.1 Destination 
	>> The value of the [destination] message addressing property
for a message sent to an endpoint MUST match the 
	>> value of the {address} property of the endpoint component
(WSDL 2.0) or the address value provided by the relevant 
	>> port extension (WSDL 1.1). For a SOAP 1.1 port described
using WSDL 1.1, the value is provided by the location 
	>> attribute of the soap11:address extension element. 
	However, there are scenarios where the WSDL address is
overridden at runtime 
	by the programming model (for example: JAX-RPC
	The mandating of the [destination] MAP to the WSDL address in
the above text does not allow for override.   
	It forces the [destination] to be the development-time WSDL
address rather than an updated runtime address.   
	Looking back at the issue that generated this text, I wondered
whether the intent was that the [destination] should be 
	derived from the WSDL address only in the absence of additional
information (as proposal 1 of the issue below)? 
	This text was a result of issue 56: 
	It was resolved with option 1 from the f2f minutes:
	The text for option 1 is: 
	>> The [destination] property is taken from the endpoint or port
address - 
	>> derived address (WSDL 2.0) or the applicable WSDL 1.1
extension (for 
	>> SOAP it is taken from soap:address/@location). ... 
	Before opening this as an issue, what are other folk's opinions?
