title: PDFTK and removing the XFA format
body: <p>Are there any issues that can come up of removing the XFA format from a PDF form? I'm using PDFTK to fill form, and found that if forms are XFA, then PDFTK doesn't work unless I do a drop_xfa command first to create a new template form. One thing I did notice is that if I didn't do the drop_xfa, I could see the fields pre-filled on Acrobat Reader but not Acrobat Pro. Other views like Ubuntu Document Viewer, would be fine. I don't mind doing the drop_xfa but just checking is there might be issues with me doing that to forms that I am not aware of.</p>
  
  <p>Example: If the form is filled, and it's to be read on a system to grab the fields/values to process.</p>
  
  <p>Thank you in advance.</p>
