I realized, after I sent my reply, that Santosh's point wrt path validation
is important. I believe Ben indicated that he did not envision logs 
performing all
of the 5280 checks, just verifying the signatures in the path. So, I 
misspoke when
I noted that 6962-bis already called for path checking; it calls for it, 
but only
in a very superficial way.

Thus we need to decide if we believe that a sig-only check on a path 
consistent with
the CABF guidelines. I don't think it is. The Definitions section of the 
CABF guidelines
includes the following entry:

     Valid Certificate: A Certificate that passes the validation 
procedure specified in RFC 5280.
