[OpenLayers-Dev] testing OL for being prepared at the ready event

[Bart van den Eijnden]

For GeoExt we have a similar issue with Ext.onReady, we advise people who want to initialize vector layers to use body onLoad instead. It's because the VML Renderer needs document.namespaces.

Best regards,
Bart
