HTML Validation was removed from CS5
Use http://validator.w3.org/ instead.
CS5 only validates ColdFusion and XML.
Adobe "deprecated" their built in HTML validator (it's still there but you'll have to turn it on manually - unfortunately I don't have a link handy to share with you on how to do that) because it was getting behind the times and Adobe feels that online validator services are 1) easier to maintain and 2) more capable then the system that was built into Dreamweaver.
Anyway I'd recommend using this:
It works. You are right about W3C.
However, when I buy expensive Dreamweaver CS5 I consider Adobe
discourteous to sell software that don't run properly.
The software runs fine.
In this case, I think they just disabled a less than optimal feature knowing there's a better alternative online already in use by most people.
Makes sense to me.

I notice CS6 now includes the Validator service, and is turned on by default. Thanks for this Adobe
Thank you for your answer.
My question was dated January 2011. Since that date I also upgraded to CS6 where the validator is OK.
