I don't think it is, that is, I think you have found a bug in the spec.

So I would propose to change the description to:

"(DAV:deny-before-grant): All non-inherited deny ACEs MUST precede all 
non-inherited grant ACEs. This precondition applies only when the ACL 
restrictions of the resource include the DAV:deny-before-grant 
constraint (defined in Section 5.6.3)."

(Geoff, please confirm :-))
