Source/WebCore:
We need to map these HTML5 elements to appropriate ARIA roles. That mapping is:
article -> Document article
nav -> Landmark navigation
aside -> Landmark complementary
section -> Document region
address -> Landmark content info
header -> Landmark banner (unless it's in an article or section)
footer -> Landmark content info (unless it's in an article or section)
