IIRC, they are actually describing different things:  Entity as a thing in the 
world, or domain of discourse, and Entity Expression as a linguistic construct 
of the PASN.  Sometimes, in informal text, distinctions like this can be glossed 
over, but in this case I think it's safer to maintain it.

Maybe there's a reason it's never been questioned :)

I think the term "process execution" is actually quite useful for distinguishing 
the notion of (roughly) a process of Entity consumption/generation that has 
actually happened from the myriad of other possible things that could be denoted 
by "activity".  It also seems to be terminology that is quite well established 
in provenance circles, and is not confusing for non-provenance-cognoscenti.

It's only disadvantage that I see is it's being two words instead of one, but 
that seems a small price to pay here.
