Fixed in VTK CVS.

$ cvs ci -m"ENH: Provide an API to write binary XML files" 
 

/cvsroot/VTK/VTK/IO/vtkXMLWriterC.cxx,v  <--  vtkXMLWriterC.cxx
new revision: 1.5; previous revision: 1.4
/cvsroot/VTK/VTK/IO/vtkXMLWriterC.h,v  <--  vtkXMLWriterC.h
new revision: 1.2; previous revision: 1.1
/cvsroot/VTK/VTK/IO/vtkXMLWriterF.h,v  <--  vtkXMLWriterF.h
new revision: 1.3; previous revision: 1.2



You can now use:

/**
  * Set the VTK writer data mode to either:
  * - Ascii
  * - Binary
  * - Appended (default)
  *
  * This may be used only after SetDataObjectType has been called.
  */
VTK_XML_EXPORT
void vtkXMLWriterC_SetDataModeType(vtkXMLWriterC* self, int datamodetype);
