Obviously Ugo was more on the same wavelength than I.  Take my reactions
as a data point.

Good point, I wrestled with that wording and i like yours better.  I
think the informal sense is that a SERVICE should look to the outside
world as if it were a discrete component, or at least a "good" service
is one that acts as if it were decoupled from the application that
physically implements it. So, I should be able to invoke someone's
"purchase order processing service" even if that is deeply imbedded in
an SAP system or whatever, without knowing about all the implementation
complexity.
