title: Creating editable PDF using FO
body: <p>I need to convert an XML file containing data into a PDF with some editable fields, like comment boxes and digital signatures.
  For now, I am using XSLT based FO to take XML file as input and convert it into PDF file without any editable components.</p>
  
  <p>Is it possible to use FO to add editable objects as well? If yes, how?
  If no, is there a way to migrate FO based development to any other tool? (for e.g. have heard iText as an alternate solution).</p>
  
  <p>Any pointers would be appreciated.</p>
  
  <p>Regards,
  Saumya Govil</p>
