Can I use an @tag in the Facebook REST API?

I w开发者_StackOverflow中文版ant to post to my newsfeed via the old REST API. If I use OpenGraph I can include in the content @1234567.. tags to tag other people in a post. Is that possible in the REST API?

EDIT: I added a 50 point bounty on a similar question Is there a way to insert an @mention into a Facebook status update posted with pyfacebook?

This is not in the external APIs at the moment.
