You can also add extra elements if they are namespaced to avoid conflicts. For example:
<desktop:can-edit-with>gimp.desktop</desktop:can-edit-with>
This indicates that the named desktop entry file describes an application that can edit
image/png files.
Information added to the database should be static (for example, "The Gimp can edit
PNG files."), not configuration (for example, "The Gimp is the preferred editor for
PNG files."). For more information on storing configuration information, see the Shared
Configuration System Spec
[http://freedesktop.org/wiki/Standards
_2fconfig_2dspec].
After you have installed the application.xml file, run the
update-mime-database command to rebuild the output files. This program checks
that the syntax of your file is correct and merges the information in it with the informa-
tion in the other XML files in the packages directory. It then puts the rules for recog-
nizing files into one set of files and the information about each type into other files (for
example, $XDG_DATA_DIR/mime/image/png.xml) where other programs can
easily access it.
When the application is uninstalled, the application.xml file is removed. Run
update-mime-database again to remove the information from the database.

To modify screensaver application preferences, users can use the Screensaver preference
