title: Signature PADES sequential or parallel
body: <p>In signature CAdES it's possible create multiple signature sequential or parallel.</p>
  
  <p><strong>Signature parallel</strong>: in case of contract, when more people have to sign the same document. Each people sign the same document, and each signature is added to document.</p>
  
  <p><strong>Signature sequential</strong>: where person sign the entire document (signature including) previously signed from another person.</p>
  
  <p>My question is: in signature PAdES it's possible to create signature parallel?
  For signature PAdES we use itext.</p>
  
  <p>Thanks for help.
