In the case where (continuing from your example):
Document newdoc = new Document(child);

Shouldn't:
newdoc.getBaseURI().equals( newdoc.getRootElement().getBaseURI() );
be true?

If it is true, then either:

a) The Document(Element root) constructor inherits BaseURI from root
        -or-
b) The Document(Element root) constructor resets root's BaseURI to some 
default

What is the current behavior for this constructor with regards to 
BaseURIs?  a) seems wrong to me, but since I can think of no other 
reasons for preserving the BaseURI of a detached element, I think null 
is the appropriate value to return.

Am I missing something?  Is there a specific use case you're thinking 
of where preserving the BaseURI makes sense?
