* Simple tag interface used to mark schema objects that are used by some

* Basic JSON-based parsers and generators do not use schemas, but some data
* formats (like many binary data formats like Thrift, protobuf) mandate
* use of schemas.
*<p>
* Since there is little commonality between schemas for different data formats,
* this interface does not define much meaningful functionality for accessing
* schema details; rather, specific parser and generator implementations need
* to cast to schema implementations they use. This marker interface is mostly
* used for tagging "some kind of schema" -- instead of passing opaque
* {@link java.lang.Object} -- for documentation purposes.
