The UI language
The element ui:special
The inner nodes of the ui:special element are expanded without applying the default output encoding. Normally, every character data node is HTML-encoded before included into the output stream such that the characters <, >, &, and " are properly quoted. Inside ui:special this quoting is turned off.
Level: Control structure
<!ELEMENT ui:special ANY>
All page body elements are allowed.
<ui:page name="sample"> <ui:special>This outputs &nbsp;, a non-breakable space.</ui:special> </ui:page>Note that we have to write & because the XML parser requires this. This page generates the string "This outputs , a non-breakable space." Without the ui:special element, the page would be expanded to "This outputs &nbsp;, a non-breakable space."
