  XSMultiValueFacet | Describes a multi-value constraining facets: pattern and enumeration.
  XSNamedMap | Objects implementing the `XSNamedMap` interface are used to represent immutable collections of XML Schema components that can be accessed by name.
  XSNamespaceItem | The interface represents the namespace schema information information item.
  XSNamespaceItemList | The `XSNamesaceItemList` interface provides the abstraction of an immutable ordered collection of `XSNamespaceItem`s, without defining or constraining how this collection is implemented.
  XSNotationDeclaration | This interface represents the Notation Declaration schema component.
  XSObject | The `XSObject` is a base object for the XML Schema component model.
  XSObjectList | The `XSObjectList` interface provides the abstraction of an immutable ordered collection of `XSObject`s, without defining or constraining how this collection is implemented.
  XSParticle | This interface represents the Particle schema component.
  XSSimpleTypeDefinition | This interface represents the Simple Type Definition schema component.

- Exception Summary
  Exception | Description
  --- | ---
  XSException | The XML Schema API operations only raise exceptions in "exceptional" circumstances, i.e., when an operation is impossible to perform (either for logical reasons, because data is lost, or because the implementation has become unstable).
