   The framework for preparation and comparison of internationalized
   strings ("PRECIS") defines several classes of strings for preparation
   and comparison.  In the framework, case mapping is defined because
   many protocols handle case-sensitive or case-insensitive string
   comparison and therefore preparation of the string is mandatory.  As
   described in the mapping for Internationalized Domain Names in
   Applications (IDNA) and the PRECIS problem statement, mappings for
   internationalized strings are not limited to case, but also width
   mapping and mapping of delimiters and other specials can be taken
   into consideration.  This document provides guidelines for authors of
   protocol profiles of the PRECIS framework and describes several
   mappings that can be applied between receiving user input and passing
   permitted code points to internationalized protocols.  The mappings
   described here are expected to be applied as Additional mapping in
   the PRECIS framework.
