Hi, Renaud,

In a nutshell, my use is a form of database publishing from two XML 
files.  The first file is *like* XSL-FO, but also contains some 
namespaced constructs.  This XML file is the page template ... it 
represents the layout, the static portions of the page, and the 
locations where various "live" data should get plugged in.

The second XML contains the live data, extracted from a database.  There 
might be thousands or tens of thousands of records of information to 
publish.

So for each main element in the live data file, we use the template 
file, but plug in the live data and generate a beautiful, formatted 
document.  The data may contain plain text, text with some formatting, 
and references to graphics and images in various formats.

It definitely needs to support "advanced" typesetting (beautiful 
paragraphs, tracking and kerning, ligatures, multiple languages, etc.).  
It needs to support full color (mostly CMYK), most widely used fonts 
(T1, TT/OT, CID, etc.)  It also needs to produce finished pages at a 
rate of thousands or tens of thousands of pages per minute.

TeX has the features I want, but I'm still trying to determine the best 
way to use it.  ConTeXt is particularly attractive for its built-in XML 
support, simplefonts support, pdfTeX support and minimals packaging, 
among other things.
