Of course. I dont mind helping out on it either, just havent had time 
lately to say I'd take ownership of it. Would at a minimum want to test 
it as it progresses.

One thing I was thinking about that may be handy is allowing a callback 
funtion as an argument - though not a necessity as the subtreee can 
always be walked a second time. Not sure how other implementations 
handle it, but moving a subtree will require the PHP implementation to 
update its doc references and counters, internal objects, etc.. which 
are stored within _private of nodes. A callback function passing the old 
doc or new doc (depending upon when it gets called) and the node would 
be a nice to have, but as mentioned not a necessisty.
