Match first arguments that contain a bus or interface name with the given namespace.

Match first arguments that contain an object path that is either equivalent to the given path, or one of the paths is a subpath of the other.

Don't actually send the AddMatch D-Bus call for this signal subscription. This gives you more control over which match rules you add (but you must add them manually).

No flags set.
