      public class ComparisonException
      extends java.lang.ClassCastException

  A `ComparisonException` is a `ClassCastException` that encapsulates an `XPathException`. It is used because the `compareTo` method is defined to return `ClassCastException` when values are not comparable; using a `ClassCastException` that encapsulates XPath error information enables us to return the correct error code, and to distinguish dynamic errors from type errors.
