Check out Updated Web Services Policy Specifications

WS-Policy and WS-PolicyAttachment have been republished based on community feedback. Updates include enhancements to the policy framework.

List of changes are:

• Updated all the examples to use Policy Assertions from 2005/07 Web Services Security Policy and 2005/02 Web Services Reliable Messaging Policy; plus, few editorial changes
• Removed @targetNamespace because it is redundant
• Added optional wsp:Policy/@Name to identify a Policy Expression using a URI
• Removed wsp:UsingPolicy (use @wsdl:required on wsp:PolicyReference instead) because it is redundant
• Prohibited circular references with wsp:PolicyReference
• Promoted WS-Security Policy’s Nested Policy Expression to WS-Policy Framework based on feedback from the security community

At Microsoft, I am a technical diplomat and responsible for standardizing and building industry momentum around WS-Policy specifications. For this publication, I had the pleasure of working with specification authors from BEA, IBM, Microsoft, SAP, Sonic Software and VeriSign.
