    - #### checkTypeDerivation

          public static void checkTypeDerivation​(ComplexType derived,
                                                 SchemaType base,
                                                 int block)
                                          throws SchemaException

      Check that a type is validly derived from a given type. This method is used only for complex types.
      Parameters:
        `derived` - the derived type
        `base` - the type from which this type is derived
        `block` - the derivations that are blocked by the relevant element declaration
      Throws:
        `SchemaException` - if the derivation is not allowed

    - #### elaborate

          public void elaborate​(SchemaCompiler compiler)
                         throws SchemaException

      Elaborate the schema component: after reloading a serialized schema component model, this expands the component with derived information needed during validation episodes. The model is assumed to be valid.
      Specified by:
        `elaborate` in interface `UserSchemaComponent`
      Overrides:
        `elaborate` in class `SchemaStructure`
      Parameters:
        `compiler` - the schema compiler
      Throws:
        `SchemaException` - if the schema is found to be invalid

    - #### serialize

          public void serialize​(SchemaModelSerializer serializer)
                         throws XPathException

      Serialize the schema component
      Specified by:
        `serialize` in interface `SerializableSchemaComponent`
      Parameters:
        `serializer` - the object responsible for performing the serialization
      Throws:
        `XPathException` - if serialization fails

    - #### getComponentAsFunction

          public Function getComponentAsFunction()

      Description copied from interface: `SchemaComponent`
      Get the schema component in the form of a function item. This allows schema information to be made visible to XSLT or XQuery code. The function makes available the contents of the schema component as defined in the XSD specification. The function takes a string as argument representing a property name, and returns the corresponding property of the schema component. There is also a property "class" which returns the kind of schema component, for example "Attribute Declaration".
      Specified by:
        `getComponentAsFunction` in interface `SchemaComponent`
      Returns:
        the schema component represented as a function from property names to property values.
