What is missing?

The reveal component does not fully conform to the design pattern described by the WAI.

The dialog container element has aria-modal set to true.

What is wrong now ?

The attribute is missing on the reveal's container.

Possible Solution

Add an aria-modal="true" on the reveal element.
Example with the documentation's accessible reveal :

<div class="reveal-overlay" style="display: block;">
  <div 
      class="reveal" 
      id="exampleModal11" 
      aria-labelledby="exampleModalHeader11" 
      data-reveal="1sx75a-reveal" 
      role="dialog" 
      aria-hidden="false" 
      data-yeti-box="exampleModal11" 
      data-resize="exampleModal11" 
      style="display: block; top: 190px;" 
      tabindex="-1"
      aria-modal="true"
  >
    <h1 id="exampleModalHeader11">Label for the Modal!</h1>
    <p class="lead">I am even more accessible than the other modals.</p>
    <button class="close-button" data-close="" aria-label="Close Accessible Modal" type="button">
      <span aria-hidden="true">×</span>
    </button>
  </div>
</div>
