Let's look at this the oehr way around.
We define an abstract namespace.
We note that currently, DNS could help implement a lookup
mechansim for it.
We implement a DNS version
Later, maybe we implement a different lookup system.
The abstract name space doesn't change.
For example, why not make subtree of DNS for finding
ISO public identifiers?
