WPML compatibility

This is David from the WPML compatibility team.
We had a few reports about WPML not working well together with Google XML Sitemaps and tried to find a workaround for our common users.

The main problem is that Google XML Sitemaps uses custom DB queries and WPML doesn’t hook on custom queries to modify them.

I wrote this little snippet and so far it has been working for our users:

if ( defined( 'ICL_SITEPRESS_VERSION' ) ) {
    add_filter( 'option_sm_options', 'sm_wpml_exclude' );
}
function sm_wpml_exclude( $value ) {
    global $wpdb;

    $ids = $wpdb->get_col( $wpdb->prepare(
        "SELECT element_id FROM {$wpdb->prefix}icl_translations"
        . " WHERE element_type LIKE 'post_%%' AND language_code <> '%s'",
        ICL_LANGUAGE_CODE
    ) );
    $value['sm_b_exclude'] = $ids;

    return $value;
}

I’m writing to find out if you are willing to include these lines in your plugin.
If you will, we can add your plugin to our list of compatible plugins:

Let me know what you think.
