Try:
namespace itk
{

template <
   class TScalarType = double,          // Data type for scalars
   unsigned int NDimensions = 3,        // Number of dimensions
   unsigned int VSplineOrder = 3 >      // Spline order

class ITK_EXPORT  MyTransform : public BSplineDeformableTransform<
TScalarType, NDimensions, VSplineOrder >
{
public:
