Template:Proposed deletion/dated/testcases

The test cases that follow introduce boiler text in certain situations that will conceivably occur.

For example:

Because the templates documentation says "place the following text at the top of the page being proposed for deletion: {{subst:proposed deletion|concern=concern}} It is possible that an editor might save the page with the syntax in that manner. If so, the substituted code will append on the page like this: 

{{Proposed deletion/dated
  |concern = concern

  |help = 
}}

Where the template will render it as:

The sandbox will render it as:

When some might remove the redundant occurrence, leaving it as:{{subst:proposed deletion|=concern}} and some may remove the parameter altogether, like:{{subst:proposed deletion}} while others, still, might just use the shortcut as:{{subst:prod}} which in all of these cases the substitution will append the page with: 

{{Proposed deletion/dated
  |concern =
  |timestamp = 20181030221554
  |help =
}}

And the template will render as:

While the samdbox code will render it as:

And the majority will, undoubtedly, get it right and substitute something like:{{subst:proposed deletion|concern=The subject fails WP:GNG and is precluded by WP:BIO1E as well.}} which would append as: 

{{Proposed deletion/dated
  |concern = The subject fails [[WP:GNG]] and is precluded by [[WP:BIO1E]] as well.
  |timestamp = 20181030221554
  |help = 
}}

where the template renders as:

And the sandbox as:
