Hello Geert,I've found one Debian reference to a number of mark up languages that was written before potato came out, but I was wondering if there was a 'Debian standard.'
I've also found this:- http://www.isgmlug.org/sgmlhelp/g-index.htmwhich is much easier to follow, but I don't know if it is going in the right direction for Debian documentation purposes.
Any advice? Regards and thanks, David.
