Questions about SGML

[ben]

Hello,

I would like to use the SGML format for its powerful translation
possibilities, and I would like to know if it is possible to define a
new document style (different from the LinuxDoc one)?
Does anyone know some links that would explain how to customise the
sgmltools package, or to customise it through LyX (is it possible?)?

Thanks for your help, even if these questions are not really about LyX.

Bye,
BG.
