Traditionally, the management of the DNS root zone permitted only
"alphabetic" labels. As long as the root zone included only ASCII
characters, and as long as there was only one form of a label, the
restriction plainly meant that only the letters A-Z and a-z were
permitted. The advent of internationalized labels using IDNA2008
presents some complications for the restriction. One of the
complications is the meaning of the term "alphabetic" when applied to
the Unicode code points in U-labels. This memo presents a set of
principles that can be used to determine whether a Unicode code point
may be wisely included in the repertoire of permissible code points
in a U-label in a zone.
