RE: Raising an ugly issue again

Thank you for your comment - we tracked this as a Last Call comment LC73
[1].  The Working Group had several comments on the issue of
single-interface per service but there was no consensus to revisit our
design.  We believe inheritance solves some of relevant use cases, and
feel mechanisms describing other relationships between services should
be defined outside the WSDL WG.  If we don't hear otherwise within two
weeks, we will assume this satisfies your concern.
