The attribute in this DOM tree is NOT deeply nested.  Please read the 
document!!!   Comments inline:

There are likely to be only 2-5 authorities who assert the CC 
properties, therefore this argument is insignificant.

Since you need the entire fragment anyways, once again this argument is 
not valid.  JDOM build 4 ++ supports detach().

It is a well structured XML set that allows people to detach() only the 
branch they need.  Please read the document.

Only if the original ID is held into the DOM and also the entire IDREF 
capable branch is also loaded.   Even then, it is arguably a minor 
advantage (see XML-dev list from about 2001 Nov).

ARGGhG!!!!  The only thing worse than loading one DOM tree into memory 
would be to have to load two and also be dependent on a registry being 
available AND incur network lag.  Combined, this would make it at least 
5 to 100 times slower.

It is obvious by this comment that you have also not read the document. 

Please read it.
