This is a technical group, writing technical specifications. So we need to be
extremely careful in being accurate in how we describe things.
By its definition, ADSP targets the author's domain (in the From: field.) This
means that ADSP cannot be used for other domains.
However DKIM says nothing about any other field, author or otherwise. It is
equally happy with 1st-, 2nd-, 3rd-, and nth- party signatures. And /that/
really is by intent. (It always was the major enhancement of DKIM over
Domainkeys.)
ADSP is not DKIM. It relies on it, but it goes far beyond it.
DKIM does not require or expect ADSP.
You said DKIM/ADSP. The implication is that the constraint you cited is
relevant
to DKIM. But it isn't. It's relevant (and in fact essential) only to ADSP.
