The xrl accessor is used to included named content into an xml document and to replace named links with real URIs. It also contains functionality for fragment relocation and setting of text values based on xpath evaluation. Its features reflect those needed for the dynamic generation of web content.

For more details of XRL runtime see the guide.

By default xrl is strict and throws exceptions if includes cannot be resolved. Additional modes allow for tolerant behaviour...

• xrl-tolerant is tolerant of missing includes
• xrl-html produces text/html mimetyped result and is strict
• xrl-html-tolerant produces text/html mimetyped result and tolerates missing includes - good for production system
