Defines a new function. The <defarg> function must be used to declare the arguments to a function. Use the <call> function to execute the function. Functions are typically defined within forms.

Example

<defun name=’add100’>
   <defarg name=’input’/>
    <add>
       <ref>input</ref>
       <i>100</i>
    </add>
</defun>
