Just an update.....
I was looking and studying the file functions.wp-styles.php and I figured there's a code that says:
$_handle = explode('?', $handle);
this makes me to think I could write something like:
but when I look inside class.wp-styles.php I see this:
echo apply_filters('style_loader_tag, ', "<link rel='stylesheet', href='$href' type='text/css' media='$media' />\n", $handle);
so that makes me asking myself: how I can now reproduce a result like:
<link rel='alternate stylesheet' title='alternate_gallery' href='alternate_gallery.css' type='text/css' media='screen' /> ?
Thanks to all!
