+There is currently no standard way to express language and text direction
+information in JSON. Implementers and authors are urged to read guidance
+regarding the expression of internationalized string values in the "Strings on
+the Web: Language and Direction Metadata" document [[?STRING-META]].

+The example below is one way in which an author could encode language and text
+direction in JSON data that is secured using this specification.
