I decided not to use FDF or AcroForms / XFA to create the output PDFs. I just thought it would be easier to render the data as plain text, shapes, and images. However, I do parse form fields from AcroForms / XFA forms. I'm not sure about the pros and cons. If a customer needed to generate PDFs with data in the FDF format, then that's something that I would be happy to build.
