From the link you gave, we stick on <http://www.w3.org/TR/html401/types.html#type-uri>, so it references an IETF RFC <http://www.ietf.org/rfc/rfc1808.txt> that describes what is an URI.

The fourth section describes how we have to determine the resolution of an URI. The point that are in our scope is the next I quote :

«
a) If the embedded URL is entirely empty, it inherits the
              entire base URL (i.e., is set equal to the base URL)
              and we are done.
»

  If you have any doubt, just enjoy reading the full document ;)

But for me, it is quite clear that an empty string is a valid URI *into* a document served by HTTP.
