I don't understand what you mean by that.


I meant to say that the namespace is not being dereferenced. In this case 
we are using the namespace simply as a name and are forming identifiers 
based on it using the URI reference syntax.

Even if the namespace might be dereferencible, it might not be a WSDL 
document. It might be a RDDL document or something else. The point is that 
we are  not assuming anything about a media type. We are just forming 
identifiers.

It's not a matter of redefining.

You can choose whether and to what extent the media type definition
of application/wsdl+xml inherits from XPointer.

I don't have any requirements for you to use XPointer at all.

I do have a requirement that you don't use XPointer's barename
definition.

I don't understand what you mean by that.

Whatever you get by dereferencing a URI should agree with other
specifications about that URI.
