It's not really about the "level of abstraction" but rather
about the purpose of the model: standard interaction protocols
correspond to domain models which you may transform into
design models (by enriching/refining them). The OMG also
calls these two different types of models "Computation-
Independent Model (CIM)" and "Platform-Independent Model 
(PIM)" in their Model-Driven Architecture approach.
