The limited feedback during WGLC has been favorable to this.

This will require a rather larger change to the document than the other 
issues, but they are manageable and I believe I have most of the relevant text 
from earlier revisions.

I think we should include this.  As discussed in the previous issue, the PSDs 
that can deploy PSD DMARC today is limited.  One of the few that are engaged 
with this effort that can has specifically requested it as a support to their 
broader DMARC deployment efforts within their PSD.  Additionally, this may have 
utility for regular DMARC and now is a good time to explore the concept.

Unless this is clearly negatively received, I'll propose specific changes to 
support it later today.  I'll also update the existing implementation that's 
mentioned in Appendix C, but probably not today.
