(Someone will shortly begin firing 22 caliber rounds into my office[1],
 so I will leave this verbose.)

  Textual inclusion is a fundamental indirection/abstraction mechanism,
  required if www is to scale in volume and duration.

 1 Inlining of dynamic/living documents is needed.
 2 This can be done at server or at client.
 3 You sometimes(often?) dont want to do it at server.

 1. What happens if you cant inline dynamic information?
      - Copying, and then either maintaining consistency or
                                 accepting obsolence.
      - Hyperlinking to it, even when you need it in flow of the doc.
      - Doing both, and push the burden onto the human.
      - Giving up.

  I have fuzzy recollection of a cern doc which mentions brewster at
TMC in cambridge.  He switches jobs.  Does tim 1- leave it outdated
(print model), 2- hand edit it every time brewster moves (toy system
model), or what?
  What if I wish to inline's phone number or mailing address?
  Suppose I write a living document criticizing unix.  To illustrate
my point, I wish to quote some single FAQ entry.  Do I 1- copy it, thus
losing the benefit of improvements to the FAQ, 2- point to it, forcing
me to use a document structuring I didnt want, 3- periodically hand
edit it (not), 4- have an agent edit it, n- or what?
  Can I create a composite document with out either losing consistency
or looking like a gopher menu?
  Inlining, by virtue of making the web representation more powerful,
might be used to address other problems.
Caching might be addressed by something (remotely) like
<A HREF=<INLINE HREF="http://wwwnamed-host/cern-cache">/pub/mumble>cern</A>.
WWW cache inheretence then follows the DNS hierarchy.

Must go.
