There was the Holy Grail, then Sasquatch and now...

Unicorn.

W3C Validation services are being offered as a bundled service;
"one-stop shopping." <http://validator.w3.org/unicorn/> (The server's
been molasses-slow, btw). Here's a good blurb from Webmonkey
contributor Michael Calore:

> Want to find out how magically terrible your web code is? Just ask
> the Unicorn.
>
> The web�s governing body has launched a new validation tool called
> Unicorn that checks the quality of your website�s code against
> multiple web standards at the same time.
>
> You can find the new Unicorn �all-in-one validator� on the Worldwide
> Web Consortium (W3C) website at validator.w3.org/unicorn/.
>
> The W3C maintains a number of free web-based tools for checking
> whether your web code is valid, and Unicorn makes several of these
> tools available under a single interface. Just plug in a URL and you
> can see your results for all of these tests on a single page:
>
> * HTML/XHTML markup validator
> * CSS validator
> * Atom or RSS feed validator
> * mobileOK, which tells you how friendly your site is to mobile
> visitors
