Comment:

 <section title="Comparison, Equivalence, Normalization and
 Canonicalization">

 <t>In general, when considering a set of items or strings, there are
 several
 interrelated concepts. A comparison method determines, between two items
 in the
 set, their relationship. In particular, a comparison method for
 determining
 equivalence might result in a determination that two (different) items are
 equivalent,
 known to be different, or that equivalence isn't determined.  </t>
 <t> One way to define a comparison for equivalence is to define a
 a normalization or canonicalization algorithm. For each item in a set
 of equivalent items, one of them could be designated the "normal" or
 "canonical" form. </t>

 <t>These general concepts are used with IRIs in this document,
 and in other circumstances, where a mapping from one sequence of Unicode
 characters to another one could be described as a "normalization"
 algorithm.</t>
 <t> In general, this document tries to stay with the "equivalence" or
 "comparison" methods, become some times the mathematical notion of
 "normalization" results in forms that ordinary users might not consider
 "normal"
 in an ordinary sense.
