W3C Markup Validator Upgraded
W3C is pleased to announce an upgrade to the W3C Markup Validation Service. The new release is easier to use and install. It features new documentation and navigation, and offers helpful explanations and recovery mechanisms instead of fatal errors. Managed by a team of volunteers and the W3C Quality Assurance Activity, and supported by a large community, this validator is the single most popular resource on the W3C Web site.
