An expansion function is associated with a substitution variable (also known as a field) in a template. Whenever that variable is substituted in the template, the expansion function is invoked to provide a value for the substitution. The expansion function is defined as a name that takes zero or more parameters. This name is associated with an actual code function that does the work required to produce the value. The IXMLDOMNode parses the expansion function and creates an ExpansionFunction object that returns the required values. This ExpansionFunction object is then called upon to return the appropriate value for the variable each time the variable is substituted in the template.
