Currently the HTML5 header element has an AXRoleDescription="banner". This is the same description as for the ARIA banner landmark role. 
http://dvcs.w3.org/hg/html-api-map/raw-file/tip/Overview.html
It is suggested that this is incorrect as ARIA banner role semantics are not the same as the HTML5 header element. banner can be described as a special case header that conveys the particular semantics:

"A region that contains mostly site-oriented content, rather than page-specific content.
Site-oriented content typically includes things such as the logo or identity of the site sponsor, and site-specific search tool. A banner usually appears at the top of the page and typically spans the full width.
Within any document or application, the author SHOULD mark no more than one element with the banner role."
http://www.w3.org/TR/wai-aria/roles#banner

the header element has more generic semantics and does not have the same constraints as the banner role. So many headers may be included within a single document

"The header element represents a group of introductory or navigational aids."

Suggest changing to AXRoleDescription="header"
