+// Package dynamodbattribute provides marshaling utilities for marshaling to
+// dynamodb.AttributeValue types and unmarshaling to Go value types. These
+// utilities allow you to marshal slices, maps, structs, and scalar values
+// to and from dynamodb.AttributeValue. These are useful when marshaling
+// Go value tyes to dynamodb.AttributeValue for DynamoDB requests, or
+// unmarshaling the dynamodb.AttributeValue back into a Go value type.
+//
+// Marshal Go value types to dynamodb.AttributeValue: See (ExampleMarshal)

+// The ConvertTo, ConvertToList, ConvertToMap, ConvertFrom, ConvertFromMap
+// and ConvertFromList methods have been deprecated. The Marshal and Unmarshal
+// functions should be used instead. The ConvertTo|From marshallers do not
+// support BinarySet, NumberSet, nor StringSets, and will incorrect marshal
+// binary data fields in structs as base64 strings.
+//
+// The Marshal and Unmarshal functions correct this behavior, and removes
+// the reliance on encoding.json. `json` struct tags are still supported.
+// Support for the  json.Marshaler nor json.Unmarshaler interfaces have
+// been removed and replaced with have been replaced with dynamodbattribute.Marshaler
+// and dynamodbattribute.Unmarshaler interfaces.
