This is a page to display some funny things about references and DPL's. I have had the problem that DPL interacts funny with references on the other wiki's on which I work. 
Here is a reference erasing DPL.
As you can see, the references above the DPL disappear when I call the DPL. However, the references below the dpl will still show up. Note the two "1" references on the page and check the code. They do not have the same name and are different references.
