## Interface SchemaComponent

- All Known Subinterfaces:
    SchemaAnnotation, SchemaAttributeGroup, SchemaGlobalAttribute, SchemaGlobalElement, SchemaIdentityConstraint, SchemaModelGroup, SchemaType
  All Known Implementing Classes:
    SchemaAnnotationImpl, SchemaAttributeGroupImpl, SchemaGlobalAttributeImpl, SchemaGlobalElementImpl, SchemaIdentityConstraintImpl, SchemaModelGroupImpl, SchemaTypeImpl

      public interface SchemaComponent

  Represents a global Schema Component. That is, a type, element, attribute, model group, attribute group, or identity constraint.

  Note that not all types, elements, and attributes are global; local types, element, and attributes do not appear in the global lookup table. Also note that other information items such as particles, facets, and so on are not globally indexed, so are not SchemaComponents.
