== 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
 | 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
   | main  = Article text
   | other = Other pages text
   | demospace = main
  }}

The '''page''' parameter instead takes a normal pagename, making this template behave exactly as if on that page. The pagename doesn't have to be an existing page. Like this:
<pre>
{{Namespace
 | 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
   | 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 {{T|Namespace}} template. Like this:
<pre>
{{Namespace
 | main  = Article text
 | other = Other pages text
 | demospace = {{{demospace|}}}
 | page  = {{{page|}}}
}}
</pre>

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