public interface ExprDeclaredNode
extends ExprNode

Expression instance as declared elsewhere.

(1) Statement parse: Expression tree from expression body gets deep-copied. (2) Statement create (lifecyle event): Subselect visitor compiles Subselect-list (3) Statement start: a) event types of each stream determined b) subselects filter expressions get validated and subselect started (4) Remaining expressions get validated
