It would be great if pdf signatures created with PDFBox would assist in creatign those.
Target test setup:
1) input of an unsigned PDF-1.5 document
2) signature with
a) local key pair
c) remote signature service (e.g. via soap)
3) add ocsp response for LTV (crls typically are larger)
==> Result: signed pdf where acrobat reader claims it to be "LTV enabled"
