I think an architect is not a compliance officier.  An architect designs a
structure to function not to be legit.  The resolution of httpRange-14
serves the purpose but the resolution won't prevent misuse and abuse of http
URI.

Why is it not? If a resource is abstract, it cannot be manifested otherwise
it won't be an abstract resource (AR).  What we can manifeste is not the AR
but its Description. But a Description of an Abstraction is not the
Abstraction itself.  Information resource (IR) is also different.  IRs are
those resources or the Description of resources that can be manifested into
bitstreams.  Of course, IR is disjoint from AR and also disjoint from the
Representation of AR as well.
