But you didn't state anything of the like. If anybody deviates from the
SDM they had better well bloody mention it. And you being from Intel, I
would very much like to have an Official (TM) statement right along with
it. Preferably in the form of a new SDM.

Also, you didn't CC Stephane, nor was it mentioned where this
observation was made from.

In short, the typical shoddy quality one expects from you.
