Desktop Spec Question

[Allen Winter]

Howdy,

I'm trying to cleanup the KOrganizer .desktop files to meet
the desktop spec [1] by running desktop-file-validate [2] on them.

But I don't know what to do with the following warning:
% desktop-file-validate korganizer_configplugins.desktop
korganizer_configplugins.desktop: warning: value "Service" for key "Type" in group "Desktop Entry" is a reserved value for KDE

Do I 
1) ignore the warning
2) change Type=Service to X-KDE-Type=Service
3) change Type=X-KDE-Service
??
