public class PreparedSchema
extends SchemaStructure

A schema is a collection of schema components. It may be derived from a single schema document (an xs:schema element), in which case it contains those components defined in that schema document, the components defined in the included documents (expanded transitively), and the components defined in imported schema documents (not expanded transitively). Alternatively, it may be a collection of schema components derived from multiple independent schema documents.
