 +===== Discussion =====
 +
 +A Data Structure Instance is a populated occurrence of a [[dido:99_annexes:annex-b-terms-and-definitions:d:data_structure_definition|Data Structure Definition]]. It contains actual values that conform to the governing Data Structure Definition.
 +
 +A Data Structure Instance may appear as a message, record, event, assertion, command, command acknowledgement, status report, heartbeat, policy decision, release record, audit event, provenance record, or persisted entry.
 +
 +A Data Structure Instance may move through a Communication Endpoint, reside in a persistence mechanism, support an audit trail, or appear in an evidence package. It remains distinct from the Data Structure Definition that governs it.
