I think the best aproach is: make it work first, then think about making it 
simpler. I don't think people care about having to add (most likely 
cutnpaste) a few elements. If there is a better, not too expensive, way we 
can always add it later on as extra sugar.

Looks good to me.

I vote against hasAttribute, it does indeed totally defeat everything that we 
belive in. It is weak and without honour.

Give element.prototype.hasOwnProperty('style') a try, and then go for eval. 
You might want to check the elements' interfaces for other clues:

var props = '';
for (p in element) {
    props += p + ': ' + element[p] + "\n";
}
alert(props);
