TARGET: SCA WS Binding Specification cd01


The schema for binding.ws calls for the following construct:

                    <element ref="wsa:EndpointReference" minOccurs="0"
                    <any namespace="##other" processContents="lax" minOccurs="0"

Which leads to a UPA error it you try and validate against it.  For UPA see http://en.wikipedia.org/wiki/Unique_Particle_Attribution

The schema is valid in the sense that it's valid and well formed XML but you will get a UPA validation error if your .composite file has an EndpointReference element within a binding.ws element. The problem being that the validator doesn't know if the EndpointReference belongs to the <EndpointReference> or <any> schema elements.


It seems difficult to fix this kind of problem and maintain the ability to support EndpointReference validation and binding.ws extensibility without changing the structure of binding.ws. Resolution to be determined.
