I would go further: implementation and interface are just two different things and years of experience indicates that keeping them separate is better. That separation is a _major_ reason for the whole web services program. That will hold true for 1.0, 1.1, 2.0 and 10.0. IMO, the W3C should be focused on interface. Paul Prescod
