Where do we say that CPE Routers MUST NOT send RS's?

That was certainly not the intent of the draft...

I only see a requirement in RFC 4294 (and draft-ietf-6man-node-req-
bis-02) to send RS and process received RA at hosts.  There is no
language that says routers MUST NOT send RS and process received RA, as
draft-wbeebee-ipv6-cpe-router describes.

You have a point about RFC 4191 perhaps needing to be amended.  It
describes MSR as a router-to-host protocol and not a router-to-node  
protocol.  This strikes me as an oversight that should be corrected.   
I see no technical reason that only hosts and not all nodes should be
permitted to process MSR messages.
