This document specifies the syntax for URNs.  While some namespaces
   resolvers may assign special meaning to certain of the characters of
   the Namespace Specific String, any security consideration resulting
   from such assignment are outside the scope of this document.  It is
   strongly recommended that the process of registering a namespace
   identifier include any such considerations.
