Ummmm... I think this is an important issue.

URNs do not refer to living documents. URNs refer to static products.
Just as the URN is forever, the product to which it refers is forever, and
if there is some reason to change it, that change creates a new product.
If the product is for some reason no longer available, then the URN maps
to zero URLs.
