Yes, the IDs are currently incorrect; however, the publisher ID does not 
need to be an Organisation resource but should rather be registered as a 
VOEvent Publisher resource. The problem, of course, is that we have not 
yet worked out the metadata that we require to describe VOEvent 
resources in the registry. This is something we should try and get ready 
for discussion at VOEvent III/IVOA Interop.
