Recently I've been implementing ARIA into a web application and I found [this question](https://stackoverflow.com/questions/12279113/recommended-wai-aria-implementation-for-navigation-bar-menu) to be quite helpful in the improving the navigation parts.

After implementing this in all modules, I discovered this HTML validation error:

> 
> Attribute `aria-selected` not allowed on element `a` at this point.

Looking at the ARIA specification, I see that `aria-selected` is only used in roles gridcell, option, row, and tab. In my case, the role of the link is `menuitem`.

This is a representative sample of the HTML code:

```
<nav role=navigation>
    <ul role=menubar>
        <li role=presentation><a href='page1.php' role=menuitem>Page 1</a></li>
        <li role=presentation><a href='page2.php' role=menuitem>Page 2</a></li>
        <li role=presentation><a href='page3.php' role=menuitem aria-selected=true>Page 3</a></li>
        <li role=presentation><a href='page4.php' role=menuitem>Page 4</a></li>
    </ul>
</nav>

```

As you can see, this is taken on "page 3".

What is the correct ARIA role to use here?
