[RFC] Mandatory user doc in KDE review/incubation checklist

[Christoph Grüninger]

Hi Luigi,
from a technical point of view Docbook seems to be nice. Still, it is 
uncommon and is a barrier for contributors and incubating projects. 
Writing XML went out of fashion over a decade ago. By default, I don't 
have the tool-chain for Docbook installed.

I would like to see Sphinx or ReStructured Text as official alternatives 
and not getting the Docbook requirement further cemented. Where 
possible, we should reduce KDE-specific paths.

Bye
Christoph
