"description": "The ConstraintNode type is provided to support usecases in which a node in a structured data graph is described with properties which appear to describe a single entity, but are being used in a situation where they serve a more abstract purpose. A [[ConstraintNode]] can be described using [[constraintProperty]] and [[numConstraints]]. These constraint properties can serve a\n variety of purposes, and their values may sometimes be understood to indicate sets of possible values rather than single, exact and specific values.",
