Template:Incorrect namespace/doc

Usage
This template is for use in other templates in conjunction with namespace detection. It adds pages to Category:Pages with templates in the wrong namespace. The template has been designed to not work in the template namespace so templates transcluding this template can be viewed normally. The template also does not work on sub-pages titled "sandbox" or "testcases" or on TechInfoDepot:Sandbox.

Single namespace can be used instead of this template if only one namespace is specified (such as in the example below).

Parameters
The parameter inserts text in the message to specify the namespace the template in question should use.

Example
produces:

In the above example, transcluding the message box will categorise pages in the help namespace into Category:Example category and produce this template underneath the message box for pages outside the help namespace.
