>     Application protocols that make use of Unicode code points in
>     protocol strings need to prepare such strings in order to perform
>     comparison operations (e.g., for purposes of authentication or
>     authorization).  In general, this problem has been labeled the
>     &quot;preparation and comparison of internationalized strings&quot; or
>     &quot;PRECIS&quot;.  This document defines a framework that enables
> application
>     protocols to prepare various classes of strings in a way that depends
>     on the properties of Unicode code points.  Because this framework
>     does not depend on large tables of Unicode code points as in
>     stringprep (RFC 3454), it is more agile with regard to changes in the
>     underlying Unicode database and thus provides improved flexibility to
>     application protocols.  A specification that uses this framework
>     either can directly use the base string classes defined in this
>     document or can subclass the base string classes as needed.  This
>     framework uses an approach similar to that of the revised
>     internationalized domain names in applications (IDNA) technology (RFC
>     5890, RFC 5891, RFC 5892, RFC 5893, RFC 5894) and thus adheres to the
>     high-level design goals described in RFC 4690, albeit for PRECIS
>     technologies.  This document obsoletes RFC 3454.
