Is it possible to use jQuery to manipulate XUL elements?

Question

I know its possible to integrate jQuery within Firefox addons, but are we able to manipulate (animate, move, adjust transparency, etc) XUL elements themselves?

My explanation refers to jQuery 1.7.1.

My goal was to perform a fade animation within the XUL context, but errors were being thrown because jQuery wrongly assumes it is dealing with IE if jQuery.support.opacity is falsy.

The logic that populates the support Object was prematurely returning an empty Object due to the inability to interact with a DOM element created via document.createElement( "div" ). My problem was solved by using document.createElementNS:

createElementNS("http://www.w3.org/1999/xhtml", "div");

I searched the jQuery bug tracker after coming up with this solution and found the following related ticket: http://bugs.jquery.com/ticket/5206

jQuery isn't advertised as working within the XUL context and therefore the team has no plans of addressing the issue, though they should address the issue of the IE false positive. I am content with manually making this one line change in the source code for my application.
