Service as a front-end or "meta" service that provided a coherent
view of all MFD services registered with a Cloud Imaging Manager/Imaging
Device. �This service necessarily would need to be able to report all of
the service endpoints, names, and types so that a Client or Cloud Imaging
Manager would know which services were provided/registered and where, very much
like the SM System Control Service.<u></u><u></u></span></font></p>

with the Cloud Provider; it will now be the CICS that is "created"
and that the CICS will already know or poll the MFD for the supported (sub-)services
of the MFD.� These CICS sub-services (print, fax, etc) would be to be advertised
the same way Transform Service would provide a list of its (managed)
sub-services. ���I believe the PWG should table, for a later
time, any activity that defines or creates an entity "� providing a
way for use to define registration of �." �We already have lot
to handle already and individual Cloud Providers will have their own method and
processes for registration.� ��Defining an MFD common
registration process can be done later and independent of the current work.<u></u><u></u></span></font></p>

enumerates the available sub-services to the Cloud Provider Registration

available for use and to whom.� When a specific User registers with the
Cloud Provider or at some later date; it is the Cloud Provider Registration
Process that lists the available services that the specific User can be
associated with.� It would then be the Cloud Provider that will provide
the list of available services to the Client.�� Once the User has
