我可以在用html 4构建的网页中使用itemdata（microdata）吗？

Question

will it be useful or possible to use microdata (itemdata) in my web pages built with HTML 4 code like this

<div itemscope>
  <h1>Avatar</h1>
  <span>Director: James Cameron (born August 16, 1954) </span>
  <span>Science fiction</span>
  <a href="../movies/avatar-theatrical-trailer.html">Trailer</a>
</div>

Answer 1

It would depend on whether the Microdata consumer wanted to check for HTML5-ness via the doctype or otherwise, and then disallow the microdata if the page wasn't HTML5. But it's hard to think of a reason why such a consumer would wish to go to such trouble. How would it benefit from doing so?

Having said that, using itemscope without any itemprop s probably isn't going to achieve very much.
