This statement (rule C4 Section 6.1.1) appears to contradict the statement
that Code.Type "should not be used if the character string identifies an
instance of an Object Class or an object in the real world" ("Remark" in
section 8.1). In fact, Codes typically refer to objects in the real world. I
assume that the ISO 3166 country codes that the document makes reference to
are Code.Types, and that when the spec says "identifies an object in the real
world" it means the sort of reference such that "us" means United States and
"cn" means China, two real world objects. (02)
So it appears to me that the spec is broken. Yes? (03)
The distinction I was trying to make cannot be discussed in this case, and
anyway might have no bearing on the issue of Code.Type versus
Identifier.Type. (04)
I agree with Evan that the Mike Adcock paper doesn't shed any light on how I
might distinguish a Code from an Identifier. The best I can tell, neither
does the spec. (05)
