All "URIs" are also "Absolute URIs", and thus "URI references" ?

According to RFC 2396, a URI reference is of the form as follow, 

        Absolute URI | Relative URI  [ fragment identifier ]

As a result,  if all URIs can ben identified as "absolute URI", then all
URIs can also be called "URI references". 

So comes the problem as given in the subject of this mail. 

Thank you for your comment!
