43   * A single Schematron assert- or report-element.<br>
44   * An assertion made about the context nodes. The data content is a
45   * natural-language assertion. The required test attribute is an assertion test
46   * evaluated in the current context. If the test evaluates positive, the
47   * assertion succeeds. The optional diagnostics attribute is a reference to
48   * further diagnostic information.<br>
49   * The natural-language assertion shall be a positive statement of a constraint.
50   * NOTE: The natural-language assertion may contain information about actual
51   * values in addition to expected values and may contain diagnostic information.
52   * Users should note, however, that the diagnostic element is provided for such
53   * information to encourage clear statement of the natural-language assertion.
54   * <br>
55   * The icon, see and fpi attributes allow rich interfaces and documentation.<br>
56   * The flag attribute allows more detailed outcomes.<br>
57   * The role and subject attributes allow explicit identification of some part of
58   * a pattern.<br>
