toXMLString is almost always the way to go. I hit a major problem related to that early on in our application. I was passing XML objects to the server in an httpService.send(xml), this method will call toString on the objects you pass it to shove them in the HTTP parameters. if you have no children in your XML object, toString returns empty string, and it took me quite a while to figure out why the server wasn't getting any data from my flex app. Now I make sure to explicitly call toXMLString if I'm sending XML objects on my services.
I've seen plenty of other posts about this and was actually wondering why toXMLString is not the default string representation of an XML object?
