Using conditional expressions in Gnome documentations

[Gabor Kelemen <kelemeng gnome hu>]

Hi

I have just filed a bug[1] that can be solved by using conditional 
expressions in the xml. I saw several places in the 3.6 branch where 
these were used to include Ubuntu-specific changes, so I thought it is a 
good idea to add one more.

But now I see that the number of such conditional expressions was 
recently reduced[2], so I started to wonder why did this happen?

Was this reduction intentional for some technical reason, or was this 
just an oversight and I should file a bug about it?

There are other documentations (baobab, cheese, evince, evolution, 
file-roller, gedit) referring to help:gnome-help, so I'd like to know 
what should I do about them to make them work under Ubuntu. Is it okay 
to submit patches like the one at [1]?
