- All Implemented Interfaces:
    `javax.xml.transform.Result`, `Receiver`

      public class AssertionTreeBuilder
      extends TeeOutputter

  This class sits in the validation pipeline, ready (when requested) to build subtrees of the validated document for use in testing assertions against complex types. If no assertions are active, the class passes input events through unchanged. If one or more assertions is active, it builds a tree corresponding to the outermost active assertion. The nodes added to the tree will be typed. In the case of an element node, the type annotation is added during the endElement call, after testing assertions against that element, to satisfy the rule that when an assertion is evaluated, the target element has type AnyType but its attributes and descendants are typed according to the appropriate schema declarations.
