-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The empty URI reference refers to the base URI. What the base URI is depends on the document context (simplified algorithm: xml:base if available, otherwise network location of the document containing the reference). It's not in w3.org/tr, it's in the RFC that defines URIs, which I'm too lazy to dig up, Google is your friend ;-) - - Benja DuCharme, Bob (LNG-CHO) wrote: | Adobe's specification for XMP [1] tells us that the rdf:about attribute may | be "an empty string ... which means that the XMP is physically local to | the resource being described."
