Mapstraction - Jun 2008 - KML suppor- addOverlay and OpenLayers

Hi!

Currently I am using Mapstraction with ''openstreetmap'' API.
Everything works fine, I am able to load and display markers 
from dynamically created KML file with 

mapstraction.addOverlay("url of kml file");


However, OpenStreetMap API just uses Google Maps API
and this one has restricting licensing, so I have decided to
use OpenLayers API.

Now, the same map is displayed, but KML file is not loaded at all. 
I have checked the mapstraction.js file and I have found
that the case for ''openlayers'' for addOverlay function is 
commented out. Why is that so?

I have removed the comments, but nothing chaged, the map
was still displayed but again without any markers from KML
file.

Than I have replaced existing case

map.addLayer(new OpenLayers.Layer.GeoRSS("GeoRSS Layer", url));


with the following:

map.addLayer(new OpenLayers.Layer.GML("KML", url, 
               {
                format: OpenLayers.Format.KML, 
                formatOptions: {
                  extractStyles: true, 
                  extractAttributes: true
                }
               }));

For this one I am sure that it works since I use the same code in
OpenLayers-only web application.

Unfortunately, this also hasn''t produced any result in Mapstraction.
I still have the map without any markers.

Is it possible that they are perhaps loaded ''under'' the map?
Or I''m missing something else?

Viktor.
