* Container for the parameters to the {@link com.amazonaws.services.simpledb.AmazonSimpleDB#deleteAttributes(DeleteAttributesRequest) DeleteAttributes operation}.
*
* Deletes one or more attributes associated with an item. If all
* attributes of the item are deleted, the item is deleted.
*
*
* NOTE: If DeleteAttributes is called without being passed any
* attributes or values specified, all the attributes for the item are
* deleted.
*
*
* DeleteAttributes is an idempotent operation; running it
* multiple times on the same item or attribute does not result in an
* error response.
*
*
* Because Amazon SimpleDB makes multiple copies of item data and uses
* an eventual consistency update model, performing a GetAttributes or
* Select operation (read) immediately after a
* DeleteAttributes or PutAttributes operation (write) might
* not return updated item data.
