I think what he's asking for is something more akin to 
DocumentFragfment in DOM; i.e. he doesn't want to move an Element. He 
wants to move a sequence of three elements, two text nodes, a 
comment, and perhaps a few more text nodes. You might be able to do 
this using Lists. I'm not sure.

OK, I just looked at the JavaDoc and I don't think we can do that, at 
least not in the most general case. I think what we'd need would be 
an addContent(List) method. We have setContent(List) but not 
addContent(list). You could do it in two steps by retrieving the 
content of the element you wanted to put it in with getContent() and 
then using the methods of the List interface.
