I have a web service where the definitions are located in the wsdl-file and the schema in an external xsd-file.
In the xsd file, there is the schema tag, which provides an attribute 'version' that I can use to document the current version. Is there something similar in the wsdl format (WSDL 1.1)? If not, what is the best place to store a general version attribute for documentation purposes?
Please keep in mind that I do not want to achieve backward compatibility, like it is described in http://blogs.iona.com/sos/20070410-WSDL-Versioning-Best-Practise.pdf. I just want to document the version in the wsdl.
I'm not aware of a dedicated WSDL construct for specifying the version. Instead you could use the documentation element for this, maybe in a structured form like this:
<wsdl:service name="MyService1" ...>
<wsdl:documentation>
A service for ...
