69  * Ideally, we should be able to have {@link XMLInputSource}

71  * the {@link XMLInputSource#getSystemId()} method works is
72  * different from the way {@link Source#getSystemId()} method works.

75  * In a long run, we should make them consistent so that we can
76  * get rid of this awkward adaptor class.
