Dear John:
You were faster and more concise in your reply than I;-) (01)
All:
My basic opinion with any such URIs is that they can be useful if
maintained by the owner of the standard. Indeed, it would be good to
push standardization bodies into that direction. (02)
On the other hand, having a non-dereferencable URI for a code is not
more or less unique than having a three-letter string, as long as there
is another mechanism for representing the context of that three-letter
string. (03)
A datatype property holding that string does it in the same way as
importing the set of tokens into the URI name space. (04)
From the operational point of view, URIs for standards elements have
some advantages, and I am in general supporting those. But they must be
authoritative, current/maintained, and dereferencable. (05)
