XHTML/Facelets Basics

For all of the XHTML files that can be specified through the branding process, they MUST start with:

<ui:composition xmlns:ui="http://java.sun.com/jsf/facelets">

and they MUST finish up with:

</ui:composition>

Within the composition, almost any XHTML can be specified.

The one exception to watch out for are entities such as non-breaking spaces. Including these directly will cause the rendering of the page to fail, and users will see a big mess in their browser. In other words   will break rendering. Instead, the entity must be enclosed in a "verbatim" tag. Please note that another namespace is defined in the composition tag (in red below).

<ui:composition xmlns:ui="http://java.sun.com/jsf/facelets"
                xmlns:f="http://java.sun.com/jsf/core">
  <f:verbatim>&amp;nbsp;</f:verbatim>
</ui:composition>
