My intent is to defer to the relevant standards and let them decide what's 
valid or not. I don't think we should micromanage this, since it changes 
so much. (Right now HTML5 refers to RFC3066, but I'll update the reference 
appropriately to the moving-target reference rather than a specific RFC 
before we're done.)
