Can I store a non-text property in a DOM node in Javascript

I would like to store an object in Javascript in a custom attribute of a DOM node. I've tried setAttribute/getAttribute, but they convert the attribute into text.

Assume I've already done

node = document.getElementById( 'SAMPLE' );
object = { test: function( ){ stuff; } };

This doesn't work anywhere I've tested

node.setAttribute( 'info', object );
val = node.getAttribute( 'info' ) ;

because it leaves val with a string value.

If I do

node[ 'info' ] = object;

then

val = node[ 'info' ];

gives me back my object later in my script.

Will this work in pre-HTML5 browsers like old IEs? Is it safe?
