+[[?MULTIBASE]]-encoded strings are used to encode binary data into ASCII-only format, useful in environments that cannot directly represent binary values. This specification makes use of this encoding. In environments that support data types
 for string values, such as RDF [[?RDF-CONCEPTS]], [[?MULTIBASE]]-encoded
 content is indicated using a literal value whose datatype is set to
