> ESDS is considering not only Electronic Product Codes (EPC) but more
general kinds of identifiers - so any references to 'EPC' or 'EPC
identifier' could also be interpreted as an individual ID of an object,
whether expressed as a string, a URN or specifically an EPC URN string.

A small point, but I believe you mean to say "...a URI or specifically an
EPC URI string."  There's no reason to restrict identifiers to just URNs
(which are a subset of URIs).

On the other hand, I'm not sure you'd want to allow non-URI strings, as
you'd have little hope of insuring their global uniqueness.

The correct formulation is probably "absolute URI".
