session property
Session is this node's own session, carrying its event count and its direct fan-out. It is the same shape the list and detail reads answer with, minus the last-event preview, which the tree does not fetch.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
SessionView? session;
