I just have a look at the XPathNSResolver interface.
In the Selectors spec, the selector "elm" is equivalent to "*|elm" in the case of a missing default namespace, but "ns|elm" where "ns" is the default namespace if a default namespace is declared. The XPathNSResolver interface specifically states that it must never be called with a null or empty argument. I imagine the Selectors API would want to be able to send a null argument as a way to ask for the default namespace, or be given some equivalent functionality. -- David "liorean" Andersson <uri:http://liorean.web-graphics.com/>
