[ietf-dkim] 2.1 Signers // Within an administrative domain?

[Bill.Oxley at cox.com]

If a MUA is the signer I would hope it is within its own administrative
domain. I haven't seen one yet that was outside of its own domain.
Thanks,

What is intended by this statement?  How does this relate to messages  
signed by an MUA, which is not mentioned as a possible signer?  Is  
this statement intended to preclude the use of MUA signed messages?

(Use of the word "key" appears to be a poor choice of words.)
