OpenGL expondrá algunas caracteristicas de DX10 en WinXP?

Features de DX10 expuestas a los usuarios de WindowsXP gracias a OpenGL?, me gustaría entender esto mucho mejor, para saber a qué se puede referir cuando dice " expose DirectX 10 features on Windows XP".

NVIDIA Developer Blog: "MA – The future of OpenGL looks interesting; it appears to have gained a certain drive which it lacked in recent years. The slimmed down interface of the future looks like it will simplify development for both the driver writers as well as ourselves. The extension mechanism has also allowed manufactures of high end cards to gracefully expose DirectX 10 features on Windows XP."
