 Hello

 I am one of WPML developers. WPML is plugin which allows user to make
 multilingual sites, set language information to posts etc.

 Straight to the point: we want to make it available to add  to exported
 posts/pages an information about their language. Language information is
 stored in our own tables, so we cannot use existing WXR <item> elements
 like those for taxonomies or custom fields.

 It would be perfect if before closing </item> tag would be executed
 hookable action which will echo those additional elements, coming from
 plugins such our.

 I am attaching proposed patch.

 Example of usage:
 {{{
 add_action('wxr_export_item_extra_fields',
 'here_wxr_export_item_extra_fields');

 function here_wxr_export_item_extra_fields($post) {
         echo "<testitempost id='" . $post->ID . "' />";
 }
 }}}
