1. Introduction
Many protocols and systems need to name entities. Names that look
like DNS names (a series of labels separated with dots) have become
common, even in systems that are not part of the global DNS
administered by IANA. This document reserves the label "ALT" (short
for "Alternative") as a Special Use Domain ([RFC6761]). This label
is intended to be used as the final (rightmost) label to signify that
the name is not rooted in the DNS, and that it should not be resolved
using the DNS protocol.
1.1. Requirements notation
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
