Module:Check for unknown parameters/doc

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

Usage
By default, the module makes no distinction between a defined-but-blank parameter and a non-blank parameter. That is, both unlisted x and foo are reported. To only track non-blank parameters use 1.

By default, the module ignores blank positional parameters. That is, an unlisted 2 is ignored. To include blank positional parameters in the tracking use 1.
