4.2.2.  Header Properties

   There are four special properties that may apply to particular
   headers, namely: "experimental", "inheritable", "local", 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.
