That's fine for your draft, but "overview" and friends are
about what Hector called the "batteries not included" DKIM,
pure DKIM without SSP.
Similar example: Claiming that SPF allows to indicate that
a domain is never used as RHS in sender addresses would go
too far, "v=spf1 -all" is about HELO identities and the RHS
of envelope sender addresses, the domain could be still used
as RHS of a say "purported responsible address" (PRA) under
some conditions explained in 2821bis/2822upd/4406.
