It is quite likely that the current definition of a URI will not address all the possible combinations. This particular draft addresses one of those needs, i.e. URI definition as used in the context of HTTP/RESTCONF. The question then remains is, what other formats need to be supported. YANG does allow for extensions. If this (somewhat base) definition can be extended to accomodate other formats, can we get back to adding those extensions in a separate document?

Thanks
