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.
Certifying and Approval are both based on the use of AcroForm Widgets and
therefore only work on standard PDFs and static XFA. These sign the entire PDF
and are fully supported by iText in either classic CMS or PAdES/CAdES mode.
Data signatures, however, only sign a portion of the XML data and therefore
only work with Dynamic XFA. They are based on either XML DigSig or XAdES.
This is not supported by iText.
That help?

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.
Kind regards

Julian,
iText currently only has implemented signing of AcroForm signature fields,
not of pure XFA signature fields.
Regards, Michael
