This is not a bad idea, but likely to be problematic. Some people can
get extremely aggressive if they think they "deserve" the green banner
and get something else. In such cases, you can argue all you want that
warnings are not errors, angry people won't care.

Only few of the warnings are in the "this is strictly speaking OK but
very likely to cause problem" realm, mostly they are "I had to use some
guessing, and if the guessing was wrong, it may twist the results, so
please double-check". 

e.g: http://qa-dev.w3.org/wmvs/HEAD/check?uri=http://qa-dev.w3.org/wmvs/HEAD/dev/tests/sgml_customdtd.html

For these reasons, I think we should be extremely careful with the way
we make warnings prominent on otherwise valid/conforming documents.
Maybe a solution would be to have 
[[ Result:  	 Passed validation, 4 warning(s) ]]
be less "green", or include the little warning sign?

What do you think?
