The jquery data() function allows you to associate arbitrary data with dom elements. Here's an example.

You can do something like this to extract the value you want from javascript instead of an attribute

<a href='#' class='click'>
    <span style='display:none;'>value for javascript</span>some text
</a>

In HTML5: yes: use the data- attribute.

 <ul>
  <li data-animal-type="bird">Owl</li>
  <li data-animal-type="fish">Salmon</li>
  <li data-animal-type="spider">Tarantula</li>
</ul>

Yes, you can, you did it in the question itself: <html myAttri="myVal"/>.

You can set properties from JavaScript.

document.getElementById("foo").myAttri = "myVal"

You can add custom attributes to your elements at will. But that will make your document invalid.

In HTML 5 you will have the opportunity to use custom data attributes prefixed with data-.
