I think an   argument like "a  bibliography  in a  document does   not
contain all the text listed in the referenced books or  papers" should
be  sufficient. Using  the  X.500 technology  to store  "pointers"  to
documents  is fine,  using  it as a   "file transfer tool"  is totally
inadequate.
The technology should provide "hints" to another application suited to
this kind of job (e.g. FTP or FTAM or Z39.50). You cannot retrieve the
file system of a host you lookup through the DNS!
