Need to create a WSDL document defining the interfaces for registry operations
for EcoGrid. We specified them in Seattle as four methods:

register    <-- takes a GSH and ProxyCert as input
   delete      <-- probably rename to "unregister" to avoid conflict
   query       <-- probably same as current ecogrid query method
   notify      <-- when a registration event occurs on one node, it is responsible
                   for notifying all other registry nodes of the change -- 
                   this requires some accomodation for failed 
                   notification attempts

Matt agreed to do this. The methods might also include the methods for
maintaining a certificate authority. See bug 1163 .
