What happens to existing FBML Code once Mark Zuckerberg removes FBML?

Question

I have just added the fb:comments FBML tag to a site.

Working 100%, but Facebook has a notification on the top of the documentation that reads:

"FBML has been deprecated. Starting June 1, 2012 FBML apps will no longer work as all FBML endpoints will be removed." - Ref : http://developers.facebook.com/docs/reference/fbml/comments_%28XFBML%29/

What happens to all existing Websites and Apps that uses FBML? Will it just be disabled?

I have to switch to FBJS , I am not sure that all FBML features are available in FBJS...

Example:

I am using the following code to add the facebook comments to my website:

<div id="fb-root"></div>
<script>    (function (d, s, id) {
        var js, fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) { return; }
        js = d.createElement(s); js.id = id;
        js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
        fjs.parentNode.insertBefore(js, fjs);
    } (document, 'script', 'facebook-jssdk'));</script>

<div class="fb-comments" data-href="{URL}" data-num-posts="30" data-width="626" publish_feed="true"></div>

I have worked with FBJS before, coding a successful oAuth Login, getting the logged in status, posting to wall etc.

How would I create fb:comments in FBJS?

OR

Will FBML still work?

Answer 1

You misunderstood a couple of things here:

1. FBJS is deprecated too, I guess you mean Javascript-SDK
2. XFBML will continue to work, refer to this post.
3. Always refer to the roadmap.
4. I'm not really sure if Mark himself will remove the FBML support.

Answer 2

From the Facebook API site concerning the use of XFBML in FBJS:

The JavaScript SDK lets you use the XFBML implementations of Social Plugins.

Social Plugins, according to their page, include the 'comments plugin', which contains XFBML, that also, when used in the FB API, maintains a structure of

<fb:comments> 

I don't know what they're deprecating in the 'FBML", but "XFBML" seems to be going strong.
