    26   * <p>A class that encapsulates the error messages being reported by the
    27   * <code>validate()</code> method of an <code>ActionForm</code>. Validation
    28   * errors are either global to the entire <code>ActionForm</code> bean they
    29   * are associated with, or they are specific to a particular bean property
    30   * (and, therefore, a particular input field on the corresponding form).</p>
    31   *
    32   * <p>Each individual error is described by an <code>ActionMessage</code>
    33   * object, which contains a message key (to be looked up in an appropriate
    34   * message resources database), and up to four placeholder arguments used for
    35   * parametric substitution in the resulting message.</p>
    36   *
    37   * <p><strong>IMPLEMENTATION NOTE</strong> - It is assumed that these objects
    38   * are created and manipulated only within the context of a single thread.
    39   * Therefore, no synchronization is required for access to internal
    40   * collections.</p>
