Hi!
A small problem while trying to use QPtrDict : the key is of type *void,
and DOM::Node isn't a pointer. 
Does another fast method exists? Else i go back to my original
proposition : a basic public class and a pointer to this basic class in
NodeImpl accesible from the DOM::Node interface so that apps which want
to add extra data to Nodes could derivate the basic class to include its
data and "plug" it into the node. Is it OK to commit this?
