I didn't use the term "reference to the URI". I think you probably misunderstood the term "URI Reference". This is the term used in RFC 3986 to mean either a "URI" or a "relative reference". In normal everyday conversation most people call these "absolute URI" and "relative URI" respectively, but those terms are from older specs. RFC 3986 decided that a "relative URI" is not a URI at all, it is (in effect) an abbreviation of a URI.

No, I think you've gone off at a complete tangent here.
