The executes relation includes the property chain realizes o concretizes. I realize the property chain is included probably b/c this is how it is defined in STATO.

However, I am skeptical that the property chain does any real work for anyone, and I don't think the notion of realizing concretizations makes much sense. I'll skip my rant about this. I would like to use this relation, but can't bring myself to do so with this property chain included.
