This should suffice to get you the local or global version based on the 
context. If not, that would be a bug.

It should never get into the except clause, if you always have a global 
service. And even if the first call raises an exception, the except clause 
will do the same. In either case you can just write:

   aService = zapi.getService(self.context, PrincipalAnnotationServiceName)
