XOM API for Processing XML with Java

[Elliotte Rusty Harold <elharo AT metalab.unc.edu>]

There are basically two approaches to this, and they are distinguished thusly:

Should an element created in memory (i.e. not parsed) retain the base 
URI of its parent when detached?

For instance, suppose we parse a document at http://www.example.com/ 
to build a Document object. All the elements in this document 
initially have a base URL of http://www.exmaple.com/. Now we do this:

Document doc = builder.build("http://www.example.com/";);
Element child = new Element("child");
// child.getBaseURI() returns null
doc.getRootElement().appendChild(child);
// child.getBaseURI() returns http://www.example.com
child.detach()

What should child.getBaseURI() return now? null or http://www.example.com?
