Yes, Michael nailed it. I totally forgot that for some reason toString() is
entirely incapable of spitting out XML it seems. Why won't
ObjectUtil.toString() handle it, eh? Or is the second param of
ObjectUtil.toString() needed to get at it somehow?
ok, back to finding something else to waste the time away....lol.

Douglas,
Michael has probably nailed it. As I was getting up to speed with XML I
constantly found myself baffled by my results (as reported by trace
statements) until I realized that I need to always trace xml.toXMLString() to
get the code I was actually curious about (otherwise, XML objects with
"simple" content will simply display the content, which is often blank).
