There is another important use, You can change the Name of class and properties. It's a handy feature during serialization and deserialization.

[DataContract(Name="EmployeeName")]
public class Person
{
   [DataMember(Name="FullName")]
   public string Name { get; set; }

   [DataMember(Name="HomeAddress")]
   public string Address { get; set; }
}
