Use ReturnValues if you want to get the item attributes as they appeared before they were deleted. For DeleteItem, the valid
values are:
- NONE - If ReturnValues is not specified, or if its value is NONE, then nothing is returned. (This is the default for ReturnValues.)
- ALL_OLD - The content of the old item is returned.
Constraints:

public string ReturnValues { get; set; }
