Sorry, a case of a very important detail that I did not flesh
out owing to my time crunch!
I mentioned in the first post that
this micro-document architecture supports link management.
My proposal is that when UserList.xml moves, a redirect stub
is left behind. I.e. the file (using Guido's suggested CamelCasing)
is not deleted, but its contents are just something like:
Where, blah.xml is the new location for the UserList material.
(Periodically, all redirects can be then be expunged).

I understand your points here but I still think we should go with
plain vanilla XML as the storage notation. Even if we went with
SGML, most SGML tools put inferred tags into your documents for
you whether you like it or not!

The only SGML editor I know that allows you to work on a hands-off basis
is emacs! Fully blown SGML editors like Adept, Author/Editor,
Frame etc. all canonicalize the SGML as part of the read/edit/save

Frankly, yes. There are some cool XML editing tools beginning
to appear. As part of the Pyxie project I have developed a
servicable XML editor with wxPython. With a bit of work, it could
be tailored to the documentation project to produce easy to
use, fully Python based tools for editing/maintaining the
IBM have made available a Java app. which, given a DTD will
spit out a validating, Java based XML editing app tailored to that
Henry Thomsons XED is Python/Tk based and is getting very
usable in my opinion.
Corel's Wordperfect has a ridiculously good XML editing
capability for such a cheap office suite product!
Even if we went with SGML and people used
Adept, Author/Editor, FrameMaker+SGML, whatever, the
situation would be the same - tag minimization would
be removed by the check-out/edit/check-in round trip.
