Source: Dr. S. Smith

Explanation

An ACDC is issued by the Issuer. The Issuer identifier (AID) appears in the top level of the ACDC.

Rule

Each ACDC MUST have an Issuer and MAY have an Issuee. The set of ACDCs so disclosed in a presentation exchange MUST be chained. This set of chained ACDCs define a directed acyclic graph that MUST have at least one vertex and MAY have zero or more edges pointing to other vertices.
