A conforming UA MUST ignore the rootstring.  Phrased probably a little
better it MUST treat certain parts of the header (specified precisely
by people who know the details a little better than me, informally
being everything that isn't explicitly checked) as meaningless padding
and MUST NOT take any action based on information from those sections
of the header.
