    abstract =  {RFC5280 specifies several extended key purpose identifiers (KeyPurposeIds) for X.509 certificates. This document defines a general purpose document signing KeyPurposeId for inclusion in the Extended Key Usage (EKU) extension of X.509 public key certificates. Document Signing applications may require that the EKU extension be present and that a document signing KeyPurposeId be indicated in order for the certificate to be acceptable to that Document Signing application.},
