It's essentially the same as an "in case of disagreement" warning on a
gas pump -- if a spec describes the same thing in more than one way
(say, but human-readable prose and a machine-readable formal model),
it is essential that only one of the two be normative.  The WG decided
that, in line with most W3C specs, the prose should be normative.


All the best,
