html - Is the keyword meta tag required? -


is keywords meta tag required in html document head?

it seems me not, w3 description of document structure: http://www.w3.org/tr/html401/struct/global.html. can't find anywhere directly.

the reason have heard people argumenting should present. empty. question not regarding usefulness of tag, if required or should present of reason or not.

the meta tag optional. formal rule implies content model head element, saying sub-elements except title element optional.
