Actually, it can do "some" better.  It doesn't have to be "always error" or
"always warning".  DNSViz can use the responses it has received to infer
the role of each DNSKEY and then use that to determine the severity of
DNSKEY RRset mismatch.  In the case where there is a DS or (non-DNSKEY)
RRSIG that corresponds to a DNSKEY, then it is marked as an error.
Otherwise, it is marked as a warning.  Here is the result:


Thanks for the suggestion.
