// .NAME vtkSMInputProperty - proxy representing inputs to a filter
// .SECTION Description
// vtkSMInputProperty is a concrete sub-class of vtkSMProperty representing
// inputs to a filter (through vtkSMProxy). It is a special property that
// always calls AddInput on a vtkSMSourceProxy.
// The xml configuration for input proxy supports the following attributes:
// multiple_input: For an input port that connects multiple connections
// such as the input of an append filter. port_index: The input port to
// be used.
// .SECTION See Also
