* Unnamed (positional) parameters can be added too: <code>|1|2|arg1|arg2|...</code>.

* [[:mw:Extension:Scribunto/Lua reference manual#Patterns|Lua patterns]] (similar to [[regular expression]]s) usage with parameters is also supported (such as: {{para|regexp1|header[%d]+}}, {{para|regexp2|date[1-9]}}, {{para|regexp3|data[%d]+[abc]?}}). This is useful when there are many known parameters which use a systematic pattern.

* {{para|unknown}} – what happens when an uknownunknown parameter is used. Typically use either a tracking category to place pages that use unknown parameters, or an error.

* {{para|preview}} – the text to be displayed when in preview mode and an unknown parameter is used.

* The <code>_VALUE_</code> keyword, if used, will be changed to the name of the parameter. This is useful for either sorting the entries in a tracking category, or for provide more explicit information.
