Known Subclasses:

A Node types defining selectable columns.

These are tables, subqueries, etc. This class is the basis for the annotation of tables and subqueries.

Their getFieldInfo(name)->fi method gives annotation.FieldInfos objects for their columns, None for unknown columns.

These keep their fieldInfos on a change()
