                                       javax.faces.component.UIComponent comp)

Returns the value to expose at build time for this tag handler.

Value can be retrieved directly from component in most of cases, but should be retrieved from view-scoped managed bean when the restore phase is called (as component has not been restored yet, so its value is not available to be exposed in the tree view being built).
