Creating links with attribute

[m93a]

I've been reading MathML specification and found that all the elements can have a href attribute and become a link. It would be great to have something like this in html.

Before:

<list>
 <item><html:a href="http://foo.com">Item1</html:a></item>
 <item>Item2</item>
</list>

After:

<list>
 <item html:href="http://foo.com">Item1</item>
 <item>Item2</item>
</list>

It's just an idea but I thing it's a great step towards removing another annoying HTML tag to learn (¡viva las simplicaciónes!)
