What about this? I presuppose we define in here system and domain.
An OPES system is a system organized to permit its users to obtain a single
or a coordinated set of open puggable edge services. Such a system can be
statically and/or dynamically organized by its user, the community of its
users, a host provider or any other third party. An OPES domain is the part
of an OPES system belonging to a given operator. An OPES domain is not a
sub-OPES system as it may need external ressources to provide services.
OPES domains have no incidence on the structure of an OPES system, but
they may influence its organization for different reasons such as security,
payment, quality of service, delivery parameters, etc. particularly in the
case of dynamicly prioritized organization and revamping choices.
