Put Attributes Response from the service

The PutAttributes operation creates or replaces attributes within an item. You specify new attributes using a combination of the Attribute.X.Name and Attribute.X.Value parameters. You specify the first attribute by the parameters Attribute.0.Name and Attribute.0.Value, the second attribute by the parameters Attribute.1.Name and Attribute.1.Value, and so on. Attributes are uniquely identified within an item by their name/value combination. For example, a single item can have the attributes { "first_name", "first_value" } and { "first_name", second_value" }. However, it cannot have two attribute instances where both the Attribute.X.Name and Attribute.X.Value are the same. Optionally, the requestor can supply the Replace parameter for each individual value. Setting this value to true will cause the new attribute value to replace the existing attribute value(s). For example, if an item has the attributes { 'a', '1' }, { 'b', '2'} and { 'b', '3' } and the requestor does a PutAttributes of { 'b', '4' } with the Replace parameter set to true, the final attributes of the item will be { 'a', '1' } and { 'b', '4' }, replacing the previous values of the 'b' attribute with the new value.
