Format's the distraction, that makes people imagine they know a
solution to the problem.

The *real* problem is when there are semantic changes that actually
involve different sets of data.

For instance, the new version of BIND might support DNSSEC, which
leads to a series of new kinds of DNS records.

Imagining that "oh, we're using XML, and that's a solution" is a
terrible mistake.
