The entry at http://wiki.whatwg.org/wiki/MetaExtensions for twitter:domain
links to https://dev.twitter.com/docs/cards but that page doesn't say
anything about twitter:domain, or does the "Cards Markup Tag Reference"
page at https://dev.twitter.com/docs/cards/markup-reference

If you can point me to actual user documentation from Twitter on what
twitter:domain means, I'd be happy to add validator support for it.
