* Parameter are position dependent and therefore without a qualifier!
* `<urlparam>` or `<file>` might be given.
* If there is more than one `<urlparam|file>`, only `_Pdf` or `_Zip` is possible.
* Example: ::
SELECT "||fileadmin/test.pdf" AS _File, "||fileadmin/test.pdf" AS _Pdf, "||fileadmin/test.pdf" AS _Zip
SELECT "output.pdf|Download PDF|fileadmin/test.pdf" AS _File, "output.pdf|Download PDF|fileadmin/test.pdf" AS _Pdf, "output.zip|Download ZIP|fileadmin/test.pdf" AS _Zip
SELECT "complete.pdf|Download PDF|fileadmin/test1.pdf|fileadmin/test2.pdf|id=export&r=1" AS _Pdf
