ExOM

Hi;
I would like to write a span tag that only comes into being on a mouse-over 
event. It would look similar to having a pop-up onMouseOver, but it would 
be written as a span class (layer) in the existing window (as opposed to 
generating a new window). I know that once a document is written, it cannot 
be appended in standard JavaScript, but I have heard that such things are 
possible with IE's Extended Object Model (ExOM). Since this part of the 
script doesn't have to be compliant with NN4.x (I have an adequate 
work-around), I'd like to know how it's done. I *don't*, however, want to 
be forced to work with MS proprietary languages, such as JScript, VBScript 
or ActiveX. Am I up in the night, or can this be done, and if so, please 
advise me how and direct me to resources.
TIA,
BenO
