Yes, in W3C DOM they expose it, and even stuff like the line numbers,
but they are still not really part of the XML info-model. Maybe
someone will point to the spec and say that the prefix is, but then
that's just stupid. :) Anyway, see may response to Jonathan for a
possible solution, and also regarding my doubts if it will help. I
still think that the easiest would be if you configure the document
builder factory to namespace unaware. Of course, if you also have to
use the same DOM for other purposes than reproducing an XML source
code, then that's not an option.

XML is not wrapped with the general-purpose BeansWrapper, it has a
totally independent wrapping. The only stuff that is exposed is that's
described here: http://freemarker.org/docs/xgui_imperative_formal.html
