Implementation-dependent.  I can tell you what our implementation does: the 
single returned text node is what we call a "Domlette".  It is very similar to 
DOM, but it is not quite DOM.  I think, but I'm not sure, that you can create 
a Domlette from a 4DOM node (4DOm is full DOM L2) bu importing it into a 
Domlette implementation.

In 4XPath, this node's parent is the Domlette node that represents the foo 
element.  Its sole child is the text node mentioned above.

I have to head out in a bit, so other answers will probably have to wait until 
evening.
