Unified validation service

The WC3 have come out with a unified validation service called Unicorn. This service allows you to validate the HTML, CSS, and ATOM/RSS feeds on a page all in one call. I've added a link in the navigation pane called "Validate everything" to take advantage of this.

The nice thing about this service is that the WC3 envisage adding additional validation modules to it over time. Having this link will allow you to take advantage of new validation modules without having to change your web pages each time a new module appears.

Very good idea.
