I am trying to determine the correct/best use for role=navigation in certain cases.
1) The HTML5 spec allows multiple navigation-groups to be grouped. So for example, if I have a footer containing 3 "menus" like one for site-links, one for social-links and one for legal links, I would be allowed to wrap those 3 ul's into one nav. So my question in this case is:
What is better: wrapping 3 ul's in one role=navigation or place a role=navigation on each ul?
2) Should you wrap page-links (like previous/next article or pagination) into a role=navigation?
