you are close to the solution.

Your XML looks good.

your reader should include:

class VTK_IO_EXPORT vtkfoo : public vtk???
{
public:
   vtkSetVector2Macro(TimeStepRange,int);
   vtkGetVector2Macro(TimeStepRange,int);
protected:
   int TimeStepRange[2];
};

and your *.cxx reader source code can do the following during the 
ExecuteInformation phase:

this->SetTimeStepRange(0, this->NbTimeSteps-1);


It works for me. I use PV1.5 nightly.

Cheers
