This examples shows it:

    @DP
    @Center { rragged } @Break {
    A figure caption is centered if it would fit on one line.
    }
    
    @DP
    @Center { rragged } @Break {
    A figure caption is centered if it would fit on one line.
    A figure caption is is set ragged right if it wouldn't.
    }

The contraint satisfaction engine resolves wich part of

    @Center { rragged } @Break { ... }

will take effect.

For a short text no breaking is needed for { rragged } @Break { ... }
and @Center takes care of centering the result in the remaining blank
space.

For a long text { rragged } @Break { ... } will consume all the
available width (breaking paragraph as specified).  And @Center will
simply has no blank space to center the result in and thus will be a
no-op.
