The implicit + model is very good for defining default configuration as it does not require much + configuration but is not able to cover the exceptional case, that's why we need + to combine it with an explicit model that will take precedence over the implicit + model, it is the well known principle of convention over configuration. + </para> + <para> + Currently all explicit coordination happens only in the scope of the same page. + </para> + </sect1> + <sect1> + <title>Bindings and wirings</title> + + <sect2> + <title>Event wiring</title> + + <para> + Wires JSR-286 events.
