This glossary defines some of the terms used in this specification.
          A desktop entry is a file with a name ending in the ".desktop"
          extension which conforms to the desktop
          entry specification with Type=Application.
          It describes a menu item, including a name, an icon, and what to do when the item is selected.
          Desktop entries are also known as ".desktop files."
        
          The ID to identify a desktop entry with.
          For desktop files installed in $XDG_DATA_DIRS/applications, this
          is the same as the desktop file ID defined in the Desktop Entry Specification.
          In addition, if /opt/ude is defined
          as <LegacyDir prefix="foo-"> then
          /opt/ude/Settings/bar.desktop has
          the desktop-file id foo-bar.desktop
        
          A directory entry is a file with a name ending in the ".directory"
          extension which conforms to the desktop
          entry specification with Type=Directory.
          It provides a localized name and an icon for a submenu.
          Directory entries are also known as ".directory files."
        
A "menu path" is the path to a particular menu. Menu paths are always "relative" so never start with a slash character. The path to a menu is simply the <Name> of each parent of the menu, followed by the <Name> of the menu itself. For example, "Foo/Bar/Baz" is a valid menu path.
          The canonical path to a directory entry, relative to the
          <DirectoryDir> containing the
          entry. For example, if /usr/share/desktop-directories is
          specified as an <DirectoryDir>, the relative path to
          /usr/share/desktop-directories/foo/bar.directory is
          foo/bar.directory.
