If someone ever decides to write down DOM XPath (i.e. a proper version of the DOM3XPath note), take this into account:

WebIDL interfaces

[Constructor]
interface XPathEvaluator {
  XPathExpression    createExpression(DOMString expression, 
                                      XPathNSResolver? resolver);
  XPathNSResolver    createNSResolver(Node? nodeResolver);
  object             evaluate(DOMString expression, 
                              Node? contextNode, 
                              XPathNSResolver? resolver, 
                              unsigned short type, 
                              object? result);
};
Document implements XPathEvaluator;

Indeed, you can both construct this object and access its methods on Document. Isn't the world wonderful?
