Ian Bicking: I think there's room for some more standards building on WSGI (that aren't actually extensions of the WSGI spec itself).

I put a page up on the wsgi.org site for this: http://wsgi.org/wsgi/Specifications

And I'm introducing what I think is low-hanging fruit in the specification realm: wsgi.url_vars http://wsgi.org/wsgi/Specifications/url_vars

It appears that wsgicollection was part of the motivation, which is gratifying.

I have updated wsgicollection to support wsgi.url_vars in addition to the currently supported selector.vars.
