This has come up in several of our meetings and a lot of googling for 
answers has been going on, but to very little avail. All of our 
customers want the facebook open graph protocol ( 
http://developers.facebook.com/docs/opengraph/ 
<https://developers.facebook.com/docs/opengraph/> ) implemented on their 
pages, but we need to serve our pages as text/html for browser 
compatibility, and neither xmlns-declarations or tags will validate.

If you include <meta property="og:something" value="..." /> objects, 
they do work on facebook, (served as text/html, with or without the 
namespace declarations) But I'd really like for someone to comment on if 
there is a correct/verified way versus what is "current best practices".
