Module:Check for unknown parameters/doc

This module may be appended to a template to check for uses of unknown parameters.

Usage
or to sort the entries in the tracking category by parameter

or for an explicit red error message

or to use hidden error messages which can be viewed in the HTML source

Here,,  , ...,  , are the known parameters. Any parameter which is used, but not on this list, will cause the module to return whatever is passed with the  parameter. The  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.

Currently, the module makes no distinction between a defined-but-blank parameter and a non-blank parameter. However, the code could be easily modified to only check for non-blank parameters.
