interface MetadataInterface in Zircon Profile 8.0

A container for validation metadata.

Most importantly, the metadata stores the constraints against which an object and its properties should be validated.

Additionally, the metadata stores whether objects should be validated against their class' metadata and whether traversable objects should be traversed or not.
