ACE itself is not a fundamental requirement.  however, ACE is
very nearly implied by other fundamental requirements, some of
which are not in the requirements document.  among these is the
need for existing applications and protocols, some of which cannot
deal with other than ASCII names, to be able to exchange  IDNs
both within the protocol and between applications and other
protocols.
