Yep, the highest wins seems reasonable but... comes at a cost
implementation wise and it's not always straightforward.
For example, we'd have to modify all ServiceInfo to advertise which version
of OWS they are based onto (there is no
relationship between a service version and the OWS version it implements).
Moreover, I believe that WMS 1.1 (or was it 1.0?) was not based on any OWS
version? I believe we have a custom
handler for it.
The per service configuration of excemptions makes sense too, but the
service requests coming in from
the WCS 2.0 CITE tests ask for service=GOO (and expect a OWS 2.0
exception),
at which point a per service strategy makes no sense either.
That's why I was proposing a simple global default instead, which is what
we have today, but would at
least be configurable instead of hard coded to OWS 1.0
