public static interface ContentItem.Language
The language identifier (two-letter ISO 639-1 identifier) for the language of the content item. The default is `en`
 (English). Regional variants are treated as their parent language; for example, `en-US` is interpreted as `en`. A
 language specified with the **Content-Type** parameter overrides the value of this parameter; any content items
 that specify a different language are ignored. Omit the **Content-Type** parameter to base the language on the most
 prevalent specification among the content items; again, content items that specify a different language are
 ignored. You can specify any combination of languages for the input and response content.
