Phuoc, I saw the samilar code from Report Starter Kits like you did. Could you explain to me why you define the sealed class within the regular class

public class PregnantWoman


{
	public enum Sex {Male, Female};
	



	public sealed class Baby


	{
	...
	}
	

	...
}

instead of define two seperate classes.

public class PregnantWoman

{
	public enum Sex {Male, Female};
	

	...
}

public sealed class Baby    
{
	...
}

Any benefit ? Thanks, Peter
