GPE and XFCE are desktop environments. To simplify and unify its integration, it's needed to add them to registered Categories:
1) Add GPE, LXDE, XFCE and ROX as "Additional Category" (or "Technology Category", see bug 20189)
2) Add GPE as keyword allowed in OnlyShowIn (and NotShowIn)
- Define a "List of Registered Desktops and Toolkits"
- Change texts to:
Categories can contain any key from the List of Registered Desktops and Toolkits
OnlyShowIn and NotShowIn can contain any key from the List of Registered Desktops and Toolkits.
Pro: It would be possible to register new desktop without update of the specification in two places.
Sorry for the noise, reassigning to new (since 2 years) maintainers (Ryan & David).
Finally catching up with all these freedesktop bug reports...
XFCE has been in the list for a long time, and GPE seems inactive since 2013 (*), is this request still valid ?
Also the desktop entry spec doesn't list desktop environments anymore, only the menu spec (and desktop-file-utils, for validation).
Seems like it's all fine now.
