Re: Proper use of <header> and <nav> elements

As a user I don't care much how the author structures the objects. I just
like the ability to jump to regions that the author feels are important
header, nav and footer groups. To me these objects mean. Here is where I
keep preface information  for the header. Here is where I keep my important
links for nav, and here is where I keep my post information for the footer.
To me the author can put anything they want in these fields. That is the
author's business. I just want to be able to find the info and it's role.
