<header> element has an identical meaning to the site-wide
banner landmark role, unless nested within sectioning content. Then, the
<header> element is not a landmark.
<header> element can define a global site header, described as a
banner in the accessibility tree. It usually includes a logo, company name, search feature, and possibly the global navigation or a slogan. It is generally located at the top of the page.
Otherwise, it is a
section in the accessibility tree, and usually contain the surrounding section's heading (an
h6 element) and optional subheading, but this is not required.
This element only includes the global attributes.
