No.  NAK.  Delete this "[shipped]" stuff here.  This is some new
interpretation which you are trying to sneak in here, but there has
never been any such notion before.  It's just an address, and we don't
care where the actual data came from or who put it there.

Stop.  There is no such thing as a "shipped DT".

NAK.  We have never been using any such terms before.  You are trying
to insert completely new meaning here, and I do not agree with such
interpretation.  A DT is a DT is a DT, no matter who provided it or
where it is coming from or who installed it where.

No chance.  This is the first time ever such terms come up, and we've
been using DTs for a long, long time before.

Best regards,
