A signature field seed value dictionary pre-configures the signing operation. It can restrict or suggest the filter, sub-filter, digest method, certificate requirements, timestamp URL, and appearance.

The Ff integer marks each restriction as mandatory or advisory. The DigestMethod array lists acceptable hash algorithms. The Cert entry references a certificate seed value dictionary constraining the signing certificate.

LockDocument, AddRevInfo, and AppearanceFilter control document locking, long-term validation data embedding, and appearance handler restriction respectively.
