Answer: There may be instances where you do not need to resend the actual asset, rather just update or correct the metadata associated with a file delivery, ie:audio channel mapping or language tags.
These characters are present in most character sets,so presentation or exchange of language tags or ranges should not be constrained by character set issues.
Or specification MUST choose to a map extended language ranges to basic ranges using the algorithm below, b reject any extended language ranges in the language priority list that are not valid basic language ranges, or c treat each extended language range as if it were a basic language range, which will have the same result as ignoring them,since these ranges will not match any valid language tags.
For example, the language-range"de-de"(German as used in Germany) matches the language tag"de-DE-1996"(German as used in Germany, orthography of 1996), but not the language tags"de-Deva"(German as written in the Devanagari script) or"de-Latn-DE"(German, Latin script, as used in Germany).
