Hi Tom and Tim,

If prov:pairValue 
is a sub-property of prov:entity 
<http://www.w3.org/TR/2013/PR-prov-o-20130312/#p_entity>, wouldn't it 
make prov:KeyValuePair 
part of the domain of prov:entity.

Given that we do not want to change prov:entity and it should remain 
we could make prov:KeyValuePair a subclass of prov:EntityInfluence, but 
it looks strange.

Tim, what do you think?
