Summary:                    vtkXMLCompositeDataWriter does not write blocks with
PolyData
Description: 
PolyData blocks are not written, because of this code in line 590ff:

  vtkstd::string fname;
  if(this->Internal->DataTypes[piece] <= 0) 
    {
    return fname;
    }

PolyData has DataType 0, so instead of just discarding invalid DataTypes with
values < 0 by returning only the name, the same is done for PolyData. 

This is easily fixed by replacing by:

  if(this->Internal->DataTypes[piece] <= 0) 

Then, everything works fine.

In the attached file, the bug is fixed, yet marked with a "FIXME" tag.
