When using xdg-settings to get, check or set a desktop setting, properties and possibly sub-properties are used to specify the setting to be changed.
Some properties (such as default-web-browser) fully describe the setting to be changed. Other properties (such as default-url-scheme-handler) require more information (in this case the actual scheme to set the default handler for) which must be provided in a sub-property.
An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned:
1
2
3
4

Check whether the default web browser is firefox.desktop, which can be false even if "get default-web-browser" says that is the current value (if only some of the underlying settings actually reflect that value)
xdg-settings check default-web-browser firefox.desktop
Set the default web browser to google-chrome.desktop
xdg-settings set default-web-browser google-chrome.desktop
Set the default mailto URL scheme handler to be evolution.desktop
xdg-settings set default-url-scheme-handler mailto evolution.desktop
