user-defined element properties: cross-browser?

I've noticed that this is possible in IE:

<span class='sweetfeature' myproperty='Napoleon Dynamite'
onclick="ShowProperty(this);" >
Click here for the name of a hilarious movie.
</span>

and then in a script:

function ShowProperty(e) {
alert(e.myproperty);
// or
// alert(e['myproperty']);
}

Is there a counterpart functionality in Firefox, NS, and Opera, or is this a
proprietary MSFT feature that the other browser vendors do not support?
Thanks

Depends on the doctype you use. What you showed is not valid HTML.

ciao, dhgm

The core DOM offers the getAttribute method for element objects so
if (e.getAttribute) {
alert(e.getAttribute('myproperty'));
}
is probably what you are looking for.

Thanks for the reply, Dietmar. Do I understand you correctly, that it would
be possible to achieve this user-defined property functionality
cross-browser, simply by declaring the appropriate doctype?
