Template:Para/doc

Usage
This template is for giving examples of template parameter source code (useful in template documentation and talk page discussions of template code). It must have one or two parameters itself. The first parameter is the name of the example parameter to display (this may be empty, but it must be present), and the second (optional) parameter is a value for the first example parameter or, if the first parameter is empty, an unnamed example parameter.

Examples
When using literal, pre-specified values, simply provide the value (as in the third example above). When illustrating hypothetical, variable, or user-definable values, use (as in the second example above). The same should be done for non-literal, example parameters (fourth example above).
