Overview

A named template, also known as a partial, sub-template or embedded template, is a fragment of text that is declared in one file and then rendered in-line into another template, usually defined in a different file, every time it is invoked with the template action or the include function. A sub-template is declared with the define action. A sub-template name has a name, declared when the sub-template is defined. The sub-template body may contain action and function declaration, which will be rendered when the enclosing template is rendered.
