Re: [iText-questions] [SPAM] Re: Sign existing XFA signature field
Ok, thanks for these answers. I had misunderstood the page 25 of the document. I thought PAdES part 5 was for signatures of partial forms only, that there were already some features for signing complete forms (As extracting certificates from XFA signatures of static PDF already works even with old versions of iText). I'm glad to hear that it is planned for the next year.

Well... now that I think about it: the white paper isn't entirely clear about it. It talks about digital signatures that are stored in a form field and that are visualized using widget annotations which implies AcroForm technology, but it doesn't say that XFA signatures are excluded. Maybe there should be a NOTE or a WARNING somewhere explaining that this isn't implemented yet. -- Everyone hates slow websites. So do we.

There is a LOT of mixing of terms and technologies in this thread. Let me see if I can clear a few things up. 1 - XFA forms come in both dynamic and static flavors. Dynamic have ZERO AcroForms (or any other PDF content - it's just XML), while Static XFA uses the standard PDF and AcroForm technology for the page content and XML for the data model. 2 - There are (at least) three types of signatures that a PDF file can contain - Certifying, Approval and Data.
