    var markerLayer = new OpenLayers.Layer.Markers( "Markers" );
    map.addLayer(markerLayer);
    
    var size = new OpenLayers.Size(21, 25);
    var offset = new OpenLayers.Pixel(-(size.w / 2), -size.h);
    var icon = new OpenLayers.Icon('http://path/to/marker.png', size, offset);
    
    var marker = new OpenLayers.Marker(
        new OpenLayers.LonLat(x, y).transform(
            proj.latlng,
            proj.google
        ), 
        icon
    );
    
    marker.id = "my_custom_id";
    markerLayer.addMarker(marker);
    
    
The above code does set a marker attribute called "id" to "my_custom_id", but I can't use it to get that DOM element. For example, the following doesn't work

    var elem = document.getElementById(marker.id);
    do something with 'elem'
