Re: PROV-ISSUE-647 (TomDN): Make prov:pariValue a subproperty of prov:entity? [PROV-DICTIONARY]

Hi Tim,

The group voted (back in SB) against membership being an influence.

prov-dm defines influence as follows:

Influence ? is the capacity of an entity, activity, or agent to have an 
effect on the character, development, or behavior of another by means of 
usage, start, end, generation, invalidation, communication, derivation, 
attribution, association, or delegation.

I don't understand how we can make prov:KeyValuePair 
<https://dvcs.w3.org/hg/prov/raw-file/default/dictionary/releases/WD-prov-dictionary-20130312/Overview.html#KeyValuePair> 
a subclass of prov:EntityInfluence 
<http://www.w3.org/TR/2013/PR-prov-o-20130312/#EntityInfluence> without
going against that vote and the definition.
