# RequestUCD flag - PDF/A

The request file contains a new `<RequestUCD/>` element that, when set to "True," produces the documents below in a PDF/A format. If not setting the flag, documents are produced using the standard PDF format.

By default, the value is set to NULL. The `<RequestUCD/>` exists as a sibling to the `<AncillaryOutput/>` element.
