There are many good things about ALIWEB. However, my impression from
reading the documents referenced above is that the templates must be
human generated. I am firmly convinced that any scheme which is not
almost completely automated is doomed fail. Many maintainers will
simply not create the templates and the ones who do will not keep them
up to date. I have no doubt that a human writing an ALIWEB form will
do a better job than software, but the unfortunate fact is that most
maintainers will simply not make the effort (often they cannot).

I think this should be the default. Of course, the maintainer should
be given as much flexibility as possible in eliminating titles from
the index. Of course retaining the context is desirable, but the time
for doing this is when the document is created, not when it is indexed.
The bottom line choice is between an index of 50 servers with
carefully hand-crafted templates and an index of 5000 servers with
machine generated templates which are less well constructed but up to
date. I would certainly opt for the later. I would also do everything
possible to encourage maintainers to massage their templates to improve
