 478     url="https://dbus.freedesktop.org/doc/dbus-specification.html#type-system">Type
 479     system chapter of the D-Bus specification</ulink>). For simple

 482     be formatted as <literal>true</literal>, <literal>yes</literal>,

 484     values may be specified as <literal>false</literal>,
 485     <literal>no</literal>, <literal>off</literal>, or
 486     <literal>0</literal>. For arrays, a numeric argument for the
