I don't see that as an appropriate use of the attribute - that should be a URL you can follow to get information, not a selection parameter. Textual matching against a URL is vulnerable to both format variations, e.g. in the number of / characters, and changes in the URL itself. A URL is something which is basically a free-form string aside from syntax constraints, not a specifier that can be defined precisely. In any case, we already have an attribute to publish additional subsidiary types, namely InterfaceExtension.

This pretty much says that you agree that this is an abuse of the attribute!
