Some additional information is useful for certain errors; for example, if
DNSSEC validation failed because of a broken chain of trust, it's helpful
to indicate where the break was.

However, this can be communicated very tersely, with an error code and a
DNS name.  Full-on JSON stanzas and such strike me as massive overkill.
