Change format of comment that is posted to wall using the Facebook comment box?

Currently when an user posts a comment on my site using fb:comments and checks the "Post to profile". The post that is shared on users Facebook wall shows

• the page title
• the source (url)

How can I make it also shar开发者_JAVA技巧e the other og:meta tags? So I'd love it to take the description as well.

I have come so far that, when an user comments on a page using the like button comment box popup all the needed data goes to facebook in the format i wanted. Comments on the same pages using the comment box have a different formatting. I guess it is by design from facebook.
