Editing Template:Namespace detect/doc (section)

=== Demospace and page ===
For testing and demonstration purposes this template can take two parameters named '''demospace''' and '''page'''. 

Demospace understands any of the page type names used by this template, including the '''other''' type. It tells the template to behave like it is on some specific type of page. Like this:

<pre>
{{namespace detect 
| main  = Article text
| other = Other pages text
| demospace = main
}}
</pre>

No matter on what kind of page the code above is used it will return this:

:{{namespace detect 
| main  = Article text
| other = Other pages text
| demospace = main
}}

The '''page''' parameter instead takes a normal pagename. It makes this template behave exactly as if on that page. The pagename doesn't have to be an existing page. Like this:

<pre>
{{namespace detect 
| user  = User page text
| other = Other pages text
| page = User:Example
}}
</pre>

No matter on what kind of page the code above is used it will return this:

:{{namespace detect 
| user  = User page text
| other = Other pages text
| page = User:Example
}}

It can be convenient to let your template understand the demospace and/or page parameter and send it on to the {{tl|namespace detect}} template. Then do like this:

<pre>
{{namespace detect 
| main  = Article text
| other = Other pages text
| demospace = {{{demospace|}}}
| page  = {{{page|}}}
}}
</pre>

If both the '''demospace''' and '''page''' parameters are empty or undefined then the template will detect page types as usual.
