Is schema.org's/Google Rich Snippet microformatting breaking HTML rules?

According to schema.org, this is how you are supposed to mark up your html to make use of "rich snippet" metadata that is to be gobbled up by search engines:

<div itemscope itemtype="http://schema.org/Event">

But itemscope on itself is invalid. It's a boolean value, not an attribute like itemscope="true"

I'm using PHPTAL and it refuses to process my page once it runs into this attribute. Other validators choke as well.

So is schema.org's specification just plain wrong?

It is a boolean attribute, which is perfectly acceptable in HTML5.

I expect that your parsers are just old. The W3C validation service has no issues with schema.org's formats.

Added linky: http://www.w3.org/TR/html5/common-microsyntaxes.html#boolean-attribute

Just to update this for posterity, the answer is to fully qualify boolean properties. This means using a syntax like itemscope="itemscope"
