It does to me, and I guess an explanation is in order.  Let's
say that a given live property definition does specify that its
value must remain the same on different bindings to the same
resource.  In that case, the client can depend on them being
the same and that simple little addition creates an unnecessary
contradiction between what should have been orthogonal
specifications.  There is no reason for the binding specification
to make blanket statements when there are no conditions that hold
for all live properties -- that is why we have property definitions.

Developers don't need any more guidance here.  What they need are
shorter specifications so that they don't have to waste their time
digging through meaningless tripe just to understand the interface.
