This is a space for me to track issues as I work through the examples to determine if what's stated to work as stated in the docs works as expected (or if they need adjustment).

Issue 1

{{#dpl:
|category=+Countries in Europe¦Countries in North America
|category=*Part of NATO
|headingmode=ordered
|ordermethod=category,pagetouched
|noresultsheader=<br>''no result returned''
}}

The docs state, that adding before the category "a '+' means that only the categories listed in that statement are allowed to appear as headings in the output," yet when this is done there are no category headings in the result (are these inverted or am I misunderstanding their docs?): Result:
{{#dpl: |category=+Countries in Europe¦Countries in North America |category=*Part of NATO |headingmode=ordered |ordermethod=category,pagetouched |noresultsheader=
no result returned }}

Where if a - dash is used instead, headings appear in the result, yet the documents state: "a '-' means that the categories listed in that statement are NOT allowed to appear as headings in the output (but all others)"

{{#dpl:
|category=-Countries in Europe¦Countries in North America
|category=*Part of NATO
|headingmode=ordered
|ordermethod=category,pagetouched
|noresultsheader=<br>''no result returned''
}}

Result:
{{#dpl: |category=-Countries in Europe¦Countries in North America |category=*Part of NATO |headingmode=ordered |ordermethod=category,pagetouched |noresultsheader=
no result returned }}
