Hello,

In the "ModulePrefs/Locale" section of the Gadget XML reference (link), the following is stated:

***BEGIN***

The valid values for language are ISO639-1 two-digit language codes, and for country they are ISO 3166-1 alpha-2 codes.

There are a few exceptions to the usual language rules:

Simplified Chinese: lang="zh-cn" (typically for country="cn").

Traditional Chinese: lang="zh-tw" (typically for country="tw" or "hk", Taiwan or Hong Kong, respectively)

***END***

Are the only exceptions to the ISO639-1 standard for Chinese (zh-cn and zh-tw)? What about other common variants like pt-BR/pt-PT, en-GB/en-US, etc? What's the expected behavior if the gadget only specifies the two letter code like "zh" for Chinese?

Thanks,

Dennis

For OpenSocial gadgets, the handling of the Locale section of a gadget xml is defined here...

http://opensocial-resources.googlecode.com/svn/spec/2.0.1/Core-Gadget.xml#Locale

From the spec perspective, it's valid to specify only a language. It would apply to all country codes for that language.
