4.2.5.  Header Properties

   There are three special properties that may apply to particular
   headers, namely: "experimental", "inheritable", and "variant". When a
   header is defined, in this (or any future) standard, as having one
   (or possibly more) of these properties, it is subject to special
   treatment, as indicated below.
