Fantastic. This works great! Here's my transclude:
|category = Rebuttal_Deep-Dives
|include = #Rebuttal
It returns a bulleted list of all page titles in category "Rebuttal_Deep-Dives", including all body text in page section called "Rebuttal".
It displays a link to a non-existent Template at the top of the list. This can be suppressed by creating "Template:Extension DPL" and saving it as blank. It can even be deleted at this point, and it's display will continue to be suppressed in the DPL. More info.
Since Extension:DynamicPageList3 description says it's re-written from the ground up, with improved performance, i don't see a strong reason to investigate the other two DPL extensions.
