If this helps you, as per my comment in an earlier post, I am not using 
ACLs. For instance, if I constrain access to a resource using a policy 
that only permits access to identities in a specific relationship with 
Henry Story (denoted by his WebID), how would that be construed as an 
simply being an ACL? That's logic in action.

Instead of us arguing about labels, lets talk about entity relationship 
semantics and their implications when combined linked data graphs etc.. 
Ultimately, that's what this is all about.
