Update the DSS for a signature of the document. The main purpose of this function is testing SignDoc SDK, please use updateDSS() instead. This function is available for PDF documents only. Call this function (possibly a long time) after signing field @a aFieldName, then save the document incrementally and add a document time stamp. Before applying the first document time stamp, this function should be called for all eligable signature fields. If any document time stamp has already been added, this function should be called for the last document time stamp. The signature field must have been signed with one of these methods: SignDocSignatureParameters DigSigPKCS7Detached, SignDocSignatureParameters DigSigPKCS7SHA1, SignDocSignatureParameters DigSigCadesDetached, or SignDocSignatureParameters DigSigCadesRFC3161. This function does nothing if the signature field is not signed.
