Based on feedback received during Candidate Recommendation, the Web Services Addressing Working Group has released “Web Services Addressing 1.0 – Metadata” as a Last Call Working Draft. Comments are welcome through 23 February. The proposed WSDL extension element and WSDL SOAP module have been removed, and Web Services Policy assertions have been introduced into the specification. The document was formerly titled “Web Services Addressing 1.0 – WSDL Binding.”
