Hi all,

I have a question about the Web Services Addressing 1.0 - WSDL Binding [1]. 

Section 3.1 Explicit Association states that in the case of wsdl 1.1
we should specify the wsa:Action values for the messages in the
operation element's input and output child elements in the
wsdl:portType element.

WS-Trust specification[3] defines a SecurityTokenService (wsdl [2])
which has a wsdl:portType called "SecurityTokenService".
There is a "RequestSecurityToken" operation defined in this portType.
There are 4 types of requests: issuance, validation, renewal and
cancellation that can be consumed by the same "RequestSecurityToken"
operation.

BUT the WS-Trust spec[3], requires the use of different wsa:Action
values for each of the input/output messages for those different
behaviors. The spec calls each one of the behaviors 'binding's which
made me think that it expects different wsdl:bindings of the
"SecurityTokenService" portType for each of the different behaviors.
But according to [1] it not possible to associate wsa:Action values
with the input/output element in the wsdl:binding.

Is this behaviour expected by the WS-Trust spec incorrect? 

Am I correct if I say that, to have n different wsa:Action values for
the input messages' operation 'foo' we have to have n different
wsdl:portType definitions in the wsdl?

Please correct me if I have missed something :-)

Thanks,
Ruchith Fernando
