<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit" ?>

This initiator class do following things:

Creates an AnnotateDataBinder instance.
Sets the AnnotateDataBinder instance as a variable with the name "binder" stored in the component as specified in arg0 "component-path".(if arg0 is not specified, use Page instead.)
Calls DataBinder.loadAll() to initiate all UI components from the associated data source.
