// Public Instance Methods
   public bool HasLineInfo( );  
}

This interface allows XML reader classes (XmlTextReader and XmlValidatingReader) to return line and position information currently being read. If the class is reading data from a stream or other form of input, the HasLineInfo( ) method returns a boolean indicating if line information is provided.
