Referencing Remote Policy Expressions
An example for a remote policy reference is shown by the following uddi:businessService that is taken from the WS-PolicyAttachment specification:
<businessService serviceKey="…" >
<name>…</name>
<description>…</description>
<bindingTemplates>…</bindingTemplates>
<categoryBag>
<keyedReference
keyName="Policy Expression for example's Web services"
keyValue="http://www.example.com/myservice/policy"
tModelKey="uuid:a27078e4-fd38-320a-806f-6749e84f8005" />
</categoryBag>
</businessService>
The uddi:businessService is attached to a WS-Policy that accessible through the URL http://www.example.com/myservice/policy. The uddi:keyedReference represents the attachment. It is referencing the remote policy reference category system via its uddi:tModelKey and its value holds the URI of the policy document.
