Pass Through Elements

Standard Syntax:
     <%@ taglib prefix="jsf" uri="" %>

XML Syntax:
     <anyxmlelement xmlns:jsf="" />

The presence of an
attribute from this namespace on an otherwise non-JSF aware
markup element indicates that the markup element must be treated
as a JSF component that will be rendered equivalently to what is
specified directly in the Facelet page, with the added benefit
of being associated with a server side UIComponent

Please see the documentation for Java class javax.faces.view.facelets.TagDecorator.

Tag Summary

Markup element that causes a component of component-family: javax.faces.Panel with renderer-type: javax.faces.passthrough.Element to be inserted in the tree. This element is primarily intended to be used by the default TagDecorator, when no match is found as described in the javadoc for that class. The component that backs this element must implement javax.faces.component.behavior.ClientBehaviorHolder and return "click" from its getDefaultEventName() method. The list of events returned from its getEventNames() method must include the "on*" attributes below, ommitting the leading "on".
