Base directory specification

[Sanel Zukan]

Hi to all,

I am currently implementing Base directory specification for EDE,
according to documentation located at:
http://standards.freedesktop.org/basedir-spec/basedir-spec-0.6.html

There is stated: "If $XDG_DATA_HOME is either not set or empty, a 
default equal to $HOME/.local/share should be used." 

Here is, at least for me, unclear whether desktop should set $XDG_DATA_HOME,
$XDG_CONFIG_HOME, etc. when they are not present and point them to
default locations ?

I checked in Xfce and KDE, and I find out that Xfce sets some of them, 
but KDE does not at all.

Thanks,
