 * Helper class that is used to defer construction of {@link URL}

 * incoming System Id may not even resolve properly.
 *<p>
 * Note that class is meant to be accessed from a single thread, and
 * is not designed as multi-thread safe. Specifically it is not to be
 * used for caching or as a key, but strictly as System Id for processing
 * of a single XML document.
