Subject: NEW ISSUE: UPA in web service binding with EndpointReference
- From: Simon Holdsworth <simon_holdsworth@uk.ibm.com>

TARGET: SCA WS Binding Specification
cd01
DESCRIPTION:
The schema for binding.ws calls for
the following construct:
<sequence>
<element ref="wsa:EndpointReference"
minOccurs="0"
maxOccurs="unbounded"/>
<any namespace="##other"
processContents="lax" minOccurs="0"
maxOccurs="unbounded"/>
</sequence>
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.
PROPOSAL:
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.
