Why can the XMLList object with a single node and no subitems be used as 
a dataprovider for a list driven item, such as a tree, but I can't dump 
it out using the inherited toString() method?

For an example, please take a look at the following simple flex app.  It 
contains two trees, each populated with data from an XMLList object. 
One of those has only a single node with no subitems, the other has a 
single node with one subitem.

As you can see, in both cases, the data shows up in the tree items 
exactly as you would expect.  But when I try to dump it to a textarea, 
the XMLList object with the single node and no subitems doesn't appear.

I have read the documentation on XML on livedocs and looked at the 
XMLList documentation as well.  Allegedly, the answer to my question is 
in there but I can't find it.
