[Ontology-editors] Comprehensible examples

[David Hill]

Maybe you can make the same inference. I don't think Tanya and I ever 
looked at this exhaustively. We were just not comfortable with it because.

A regulates B means that the entirety of A needs to happen to regulate B
C, D, and E are part_of A

So C, D, or E don't necessarily regulate B, they are part_of a process 
that regulates B

We'll have a closer look at the examples to see if we can come up with 
one that is obvious. I think the reason they are not obvious is because 
in a normal biological context, all the parts occur and so does the 
regulation.
