No attributes were defined at the time of this // document's publication. // // A 'keyword' is a sequence of subtags consisting of a 'key' subtag, // followed by zero or more 'type' subtags (so a 'key' might appear // alone and not be accompanied by a 'type' subtag). A 'key' MUST // NOT appear more than once in a language tag's extension string. // // ... // // Only the first occurrence of an attribute or key conveys meaning in a // language tag. When interpreting tags containing the Unicode locale // extension, duplicate attributes or keywords are ignored in the // following way: ignore any attribute that has already appeared in the // tag and ignore any keyword whose key has already occurred in the tag. // // The duplicates itself are removed in CanonicalizeUnicodeLocaleId, step 2-3.
