verifiers and editors should of course be error intolerant so that
well formed documents are prepared......
however BROWSERS should be error tolerant to allow the viewer
to get the message even if there is a bit of noise in it.....

the web is about COMMUNICATIONS, not about correctness.
the more correct we are, the better our image but if the 
content isnt there or meaning passed to receiver then the most
correct document is useless.......

having done my editorial for the day and if Amaya Is a BROWSER
that MAY receive a bad colour situation   then what should it do ------
[1] neglect the command and use no color --- that is go to default setting
[2] set the color to black !!!!
i think #1 is correct option as this leaves things readable (not correct
but readable)  
if it were an editor/verifier  it should raise an error message saying gris
is not an acceptable colour .....

no the reason is that many do not validate at all ......
how many people even use their spellcheckers when 
virtually every wordprocessor and mail utility has them built in!
