Hreflang Tag great for Google, what about Bing or others?

[MikeSEOTruven]

I've read that the Hreflang Tag is all the rave for International solutions on a per page basis. I haven't read much about what International agencies are using for non-Google search engines such as Bing. Is the common language meta tags the only solution? would love to see an article that addresses this

I'm pretty sure meta language is the only thing Bing recognizes for language at this point.

Or the alternative syntax would be:

If the site is only targeting a language, the latter would suffice. However, if you are targeting to language and country (e.g. Spanish for Spain vs. Mexico), use the first option.
