SSDL

A new Web Services Description has been released:

The SOAP Service Description Language (SSDL) is a SOAP-centric contract description language for Web Services. SSDL enables developers to publish and share descriptions of the messages and message exchange patterns that a Web Service supports. The SSDL work was developed as a vehicle for exploring ideas in the areas of contract and protocol description, and has now been released to the Web Services community for feedback.

I think that one of the main features of WSDL is its SOAP independence. I don’t think that the services described must tightly-coupled with SOAP. Anyway, is another variant to consider.
