@cindex Named SS
Compound components are systems described by bond graphs and implemented
by MTT. They have special SS components, Named SS components
(@pxref{Named SS components}), to indicate connections to the
encapsulating system.

Like any other system, they are described by a graphical Bond Graph description
(@pxref{Language fig (abg.fig)}), and a label file (@pxref{Labels (lbl)}).

By convention, all of the files describing a component live in a
directory with the same name as the component.

In addition to the label there are two information fields, @pxref{Labels
(lbl)}. The first must be `SS', the second contains two information
fields of the form info_field_1,info_field_2.

@strong{MTT} supports parameter-passing to  (@pxref{Parameter passing})
subsystems.
