4.4. Language Identifier
This data structure consists solely of a name/value pair, where the name is "lang" and the value is a string containing a language identifier as described in [RFC5646].
"lang" : "mn-Cyrl-MN"
The "lang" attribute as defined in this section MAY appear anywhere in the object tree, in which case, it specifies the language of the object and all child objects. New instances appearing in any child object replace the previous instance for that child and its children. The language identifier is either the two-letter code specified in [ISO.639.2020] or a longer language tag as specified by [RFC5646].
