HTML Checking for Large Sites

Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.

When the itemtype attribute is specified on an HTML element, the boolean attribute itemscope must also be present in that element.

Here’s an example of how to use the itemscope attribute with the itemtype attribute:

<div itemscope itemtype="">
  <p><span itemprop="name">Liza Jane</span></p>
  <p><span itemprop="email"></span></p>

In this example, the itemscope attribute is used to indicate that the div element is a microdata item, and the itemtype attribute is used to specify that the type of this item is

If you don’t need to specify a type for the data represented by the HTML element, you can simply remove the itemtype attribute. For example:

<div itemscope>
  <p><span itemprop="name">John Doe</span></p>
  <p><span itemprop="email"></span></p>
