[flexcoders] Dynamically Adding XML Elements witih Namespaces

[Harris Reynolds]

Anyone have a clue how to dynamically (using ActionScript) add a 
child element to an XML document that is in a namespace that is 
already declared?

Below is a simple example that shows what I'd like to do, but is 
broken.  This should be so simple, but I am getting an error saying 
the element isn't bound to the namespace.

thanks,

                        dynamicElement.setNamespace(ns);
                        xml.appendChild(dynamicElement);
