Yes, it's a valid URI reference, but not a valid URI.

Not quite.

According to the standard, URIs and URI references are not the same,
see http://en.wikipedia.org/wiki/Uniform_Resource_Identifier#URI_reference
(also states "protocol documents should not allow for ambiguity").

When we talk about fragments, we actually always talk about URI
references. "In order to derive a URI from a URI reference, software
converts the URI reference to "absolute" form by merging it with an
absolute "base" URI according to a fixed algorithm." Take a look at
the standard to see the difference:
http://labs.apache.org/webarch/uri/rfc/rfc3986.html#uri-reference .

So, if we want to be correct, we should use "URI reference" everywhere.
