New desktop help system ?

[Pierre Wieser <pwieser trychlos org>]

Hi,

As I was googling searching why the help is not displayed for 
my application, I have found [1], which states:

"The desktop help has moved to the new proposed XDG help system [...]"

Though I read both desktop-devel and xdg lists, I do not remember
anything recent on the subject, and Google has not been my friend
in this matter.

Could someone give me some pointers, please ? What is this help system ?
Where is the XDG spec ? and so on...:)

Thanks in advance.

Regards
Pierre
