/**
 * @class   vtkSMDataTypeDomain
 * @brief   restricts the input proxies to one or more data types
 *
 * vtkSMDataTypeDomain restricts the input proxies to one or more data types.
 * These data types are specified in the XML with the \c \<DataType\> element.
 * VTK class names are used. It is possible to specify a superclass
 * (i.e. vtkDataSet) for a more general domain. Works with vtkSMSourceProxy
 * only. Valid XML elements are:
 * @verbatim
 * * <DataType value=""> where value is the classname for the data type
 * for example: vtkDataSet, vtkImageData,...
 * @endverbatim
 * @sa
 * vtkSMDomain  vtkSMSourceProxy
