I understood, and I'm saying in a JavaScript binding to a
browser-supplied object, the difference between attribute and property
should ideally be transparent as a matter of utmost convenience.

My emphasis is the fact that the JS and DOM are bound, therefore if it
*didn't* create the attribute - *that* would be a side-effect.

I didn't actually say that because you can't remove assignments to DOM
object properties without using removeAttribute (In IE).  The
assignment operator is no way to go about removing objects or

If anything should do the removing of attributes in the JS binding it
should be the delete operator, but unfortunately IE's browser DOM
doesn't support that action, although other browsers do.

What I said was assigning a property to null or undefined doesn't
remove the property itself, just changes its value.  It could even
create the property, if it doesn't exist, as stated in ECMA-262
section  So why shouldn't I expect it to create a DOM
