Ok, that was not the really right answer ;) Of course it does work.
You can even do stuff on that element, if you use the variable, resp.
reference ($oMyElement) for doing this.
What doesn't work (and I referred to that) is getting this object
back from the DomDocument, so for example:
$oDom->documentElement will give you the DomElement back and not your
new MyElement.
Hope it's a little bit clearer now
