I can believe that, and if necessary I can live with it. It's not 
100% clear that the ID transform described in JAXP is an XSLT 
transform though. It's not configured with any particular stylesheet.

According to the DOM2 Core spec, DOM is specifically *not* supposed 
to insert namespace declaration Attr objects into the tree just 
because a namespace is used on an element somewhere. Nor is the user 
required to provide such attributes. However, anything that 
serializes a DOM Document *is* supposed to figure out if any 
additional namespace declaration attributes are required to produce 
namespace well-formed XML and insert them where necessary.

At this point, I suspect if there is a bug it lies in StreamResult. I 
think Streamresult is seeing namespaced things but not making any 
efforts to add any necessary xmlns attributes to match.
