   Technical Summary

This document describes how algorithm identifiers can be used to
perform experiments within a DNSSECbis environment without that the
published data is marked as "bogus" by validating resolvers that do
not partake in the experiments.

The document explains why this methodology works and describes how
experiments are to be defined.

Besides, it suggests that algorithm identifiers can be used to
introduce non-backward compatible DNSSEC features into the

The technology relies on the fact that DNSSECbis validators should
treat RRSets that are signed  (exclusively) with key-algorithms that
are not implemented by the validator, should treat the RRset as
not being signed at al.

The first application of this methodology will be an experiment with
"opt-in" [draft-ietf-dnsext-dnssec-opt-in]. It is possible that the
methodology will be used for the introduction of current DNSSEC
extensions currently under development in DNSEXT, the NSEC3 work.
