Template

This text element specifies FreeMarker template code to be dynamically evaluated in-place at the current location. Templates can be used to create both RVML document fragments or text blocks and templates have full access to the entire data model defined for the document.

A Template element is permitted anywhere within an RVML document and can be specified either inline or as an external resource. The output of a template can be RVML (which can include recursive calls to the Template element) or text. When the isXML attribute is 'true' the output of the template is assumed to be XML and will be included in the RVML document at the location of the Template element. KineticFusion treats all XML templates as full XML documents and each is parsed separately. If it is necessary to create a sequence of RVML elements without a root element then the hasRoot attribute should be set to 'false' and KineticFusion will automatically wrap the XML with a 'root' root element - this will be automatically discarded on processing.

Data model variables can also be defined locally for a single Template element using the Variable child element. These consist of simple name-value pairs. If a value is set as a result of a Variable element, it is immediately restored to its previous value after the execution of the template.
