compact variant

Definition

Either a most compact version of an ACDC or the fully compact version of an ACDC. An Issuer commitment via a signature to any variant of ACDC (compact, full, etc) makes a cryptographic commitment to the top-level section fields shared by all variants of that ACDC because the value of a top level section field is either the SAD or the SAID of the SAD of the associated section.

Relationship

All the variants of an ACDC are various degrees of expansion of the compact variant.
