Source that represents an XMLInputSource. 
 Ideally, we should be able to have XMLInputSource derive from Source, but the way the XMLInputSource.getSystemId() method works is different from the way Source.getSystemId() method works. 

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