Well, xml:base= is somewhat helpful, but doesn't really solve the
problem, as it applies to *all* pointer attributes.

  <p xml:base="long://initial.url.path/here/">
    I would like to say that <name key="#LR">Laurent</name> is
    a great guy. Proof can be found
    <ref target="worse://super.long.url/path/here.xml">here</ref>
  </p>

What we'd really like is a way of saying "this is the base URI for
all key= attributes, but not others".
