In signature CAdES it's possible create multiple signature sequential or parallel.
Signature parallel: 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.
Signature sequential: where person sign the entire document (signature including) previously signed from another person.
My question is: in signature PAdES it's possible to create signature parallel? For signature PAdES we use itext.
