Thanks Michael,
Somewhat related to this, I note that the feature 'defer-node-expansion'
can not be set to false when the default document factory is used[1]. I
understand why a person might want to defer node expansion but in all of
my cases, I have to traverse every node. I am wondering, does having a
deferred node decrease performance, especially over larger documents,
when you're going to be hitting every node? If so, might it be possible
to allow adjusting the defer-node-expansion feature even when the
default factory is used?

Thanks Chad. The test was very helpful and seems to be passing now after
the fix I just committed. We have to force a full expansion of the node
being transferred while it still has a reference to its original
document and weren't doing that when both DOMs (source and target) were
initially built by a parser.
