Re: wsdli:wsdlLocation WSDL-version independent







+1 to JM's proposal as well.

Arthur:
WRT to pointing to 2 documents, wsdli:wsdlLocation [1] already allows 
this. wsdli:wsdlLocation is a list of anyURI pairs.

Even if wsdli:wsdlLocation did not allow list of anyURI pairs, given 
that wsdl 1.1 and wsdl 2.0 use different media types, one can always use 
content-negotiation (such as through the use of the Accept HTTP header) 
to get the desired version.
