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. 

Entities

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 &nbsp; 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>

Quick Links XHTML

The Quick Links XHTML is imported into the scope of an XHTML table. Any XHTML specified here should be wrapped in a <tr> and at least one <td> element.
For an example see: https://ncisvn.nci.nih.gov/svn/nbia/trunk/docs/deployment/niams_branding/quickLinks.xhtml

Other XHTML

There are no restrictions on XHTML for the welcome title/text or the footer.
