private static java.lang.String	SimplePathInterpreter.keyFromPredicate(EvalContext context, Expression predicate) Extracts the string value of the expression from a predicate like [@name=expression].
static NodePointer	SimplePathInterpreter.createNullPointer(EvalContext context, NodePointer parent, Step[] steps, int currentStep) Creates a "null pointer" that a) represents the requested path and b) can be used for creation of missing nodes in the path.
