Couldn't agree more. Once again, shall we? ;)

    URI != Universal Resource Identifier

but rather

    URI = "Uniform" Resource Identifier

Big difference. URI spans multiple namespaces - not just the HTTP URI
namespace. It's just a prescription for encoding identifiers in a uniform
manner. Therefore it's more than reasonable to assume that there may exist
identifiers from different namespaces (and minted by different naming
authorities) with the same referent - but all packaged according to the URI
prescription.
