23  /**
24   * Interceptor that validates the contents of <code>WebServiceMessage</code>s using a schema. Allows for both W3C XML
25   * and RELAX NG schemas.
26   * <p/>
27   * When the payload is invalid, this interceptor stops processing of the interceptor chain. Additionally, if the message
28   * is a SOAP request message, a SOAP Fault is created as reply. Invalid SOAP responses do not result in a fault.
29   * <p/>
30   * The schema to validate against is set with the <code>schema</code> property or <code>schemas</code> property. By
31   * default, only the request message is validated, but this behaviour can be changed using the
32   * <code>validateRequest</code> and <code>validateResponse</code> properties. Responses that contains faults are not
33   * validated.
