Just a quick observation: If you really prefer to think in terms of 
generating TeX rather than XSL-FO,  IBM published a technology 
demonstration quite some time ago which consisted of a  XML equivalent 
syntax for LaTeX and a postprocessor that would convert this into standard 
LaTeX markup.  It might still be available from the alphaWorks website.
