In the first case, the XmlValue object you get back in your result set
represents the actual XmlDocument in the container.
In the second case, what you're really getting back is an XML string,
so trying to treat it as an XmlDocument does not work.

I believe that someone suggested just using XmlValue.asString()
on the results directly.  Leave XmlDocument out of the picture,  
altogether,
(even in the first case), and you should be OK.
