Luis,

Does it make sense for me to put together a class for ITK that uses
vtkXMLPolyDataReader to construct an itkMesh/itkPointSet? It should be
pretty easy - just copy most of itkVTKPolyDataReader but change the usage of
vtkPolyDataReader to vtkXMLPolyDataReader? Or is there some reason for ITK
code to continue using the legacy vtk format? I'm not addicted to this XML
vtp format, but I already have a lot of code that uses it, and I haven't
heard suggestions for "better" formats :)

Thanks,

David
