This template is for giving examples oftemplate parameter source code (useful in template documentation and talk page discussions of template code). It must have one or two parameters itself. The first is the name of the example parameter to display (this may beempty, but itmust bepresent), and the second (optional) one is a value for the first example parameter, or (if the first{{para}} parameter is empty) an unnamed example parameter.
When using literal, pre-specified values, simply provide the value (appearance as in example 3). When illustrating hypothetical, variable or user-definable values, use<var>value</var> (appearance as in example 2), and the same should be done for non-literal, example parameters (as in example 4).
