yep - but you can write whole internet/intranet application with eXist
or ML (ML lack XSLT possibilities) in XQuery-centric mode without Java
at all (only to run eXist&Saxon) it is much better then Java or
PHP-centric application

i am eXist developer, spend about 3 years as ML developer in russian
wiley office. Still can`t find XSLT/XQuery related job here (from
january) - ML 50k$ license cost made ML very rare guest in russian
companies. So i choose to learn eXist-db instead ML and at way to
register myself as entrepreneur  - at least i can save extra 50k$ for
my customers. Even got one - Ministry of Housing in Moscow Region and
have finished first eXist-centric project for government reporting
system (Putin and Medvedev look at digits counted by my program - wow)
- by the way all numbers in reports validated by Schematron rules -
probably single government report validated by Schematron yet. Listen:
We have 10 apples - 8 to each of us - why 8 when 5? - i dunno but i am
already eat my 8.

At now i am trying to implement first (as i know) XRX-based CMS (but i
prefer term KMS - knowledge management system), also i am thinking
about eXist as base for distributed search system - probably (SKOS,
OWL, RDF)-based, and look like this KMS & distributed search system
can be merged into one project.

With best wishes,

p.s. Problem was noted by  Alan G. Carter and Colston Sanger in 1997
in Programmer's Stone book
(http://en.wikipedia.org/wiki/Programmer's_Stone) and still not solved
- conflict between "mappers" and "packers".
