Hmmm, 
sorry, I'm not that deep in PDF details ... a dynamic PDF is a PDF where 
someone filled some form with values ... isn't that the usual case for 
versioned signatures ? A first version signed with empty fields, a second 
version with new values appended, leaving the old signature intact ? And 
probably a second signature over it all ?

Or is this XFA stuff working completely different ? 

Greetings

Andreas
