However using DOM it is possible to create elements in the "" (separate from
null) namespace [1]. So an XPath implementation using a DOM, rather then a
raw XML file, will have to take this into account.

"Note that because the DOM does no lexical checking, the empty string will
be treated as a real namespace URI in DOM Level 2 methods. Applications must
use the value null as the namespaceURI parameter for methods if they wish to
have no namespace."
