A DefinedSchemaNode is a kind of SchemaNode that may be defined with the DefineLink. The sole reason for having this node type is to be able to instantly recognize when a defined node is being used (as otherwise, every atom would need to be looked up to see if it has an associated definition).

See ExecutionOutputLink and SetValueLink for usage examples.
