## com.saxonica.schema.sdoc
Class SimpleTypeDefinition

    java.lang.Object
      com.saxonica.schema.SchemaStructure
          com.saxonica.schema.UserDefinedType
              com.saxonica.schema.UserSimpleType
                  com.saxonica.schema.sdoc.SimpleTypeDefinition

All Implemented Interfaces:
  SerializableSchemaComponent, UserSchemaComponent, Serializable, SourceLocator, SchemaComponent, SchemaType, SimpleType

    public class SimpleTypeDefinition

extends UserSimpleType
implements UserSchemaComponent

A simple type definition holds all the information about a simpleType during the course of schema processing. On completion of schema processing, more specific objects are created, for example ListType, AtomicType, or UnionType, and the SimpleTypeDefinition is then discarded.
