I adding some Microdata in a page of a site. This site is standard html ,not html 5. I can add something like this without change heading of my pages?
<div itemscope itemtype="http://data-vocabulary.org/Person">
<h1 itemprop="name">Mark Pilgrim</h1>
</div>
Microdata, which includes the itemscope
and itemtype
attributes is part of the HTML5 work so there's no standard doctype available for using microdata with earlier doctypes.
I think you have to change heading of your pages to HTML5. This is probably the best way forward.
But I also think that the consumers of the microdata are unlikely to care what doctype you are using.
