How to use OpenGL ES 2.0 with OpenVG 1.1?

I have an OpenGL ES 2.0 application. I want to add some OpenVG 1.1 rendering capabilities to it so that content rendered via OpenGL ES 2.0 may co-exist and appear on screen alongside OpenVG rendered content. What is the standard/recommended way to achieve thsi via EGL native interface?

I also want to use the two APIs together such that OpenVG rendered stuff could be used as 2D texture in OpenGL ES 2.0 and vice versa?

Any help is greatly appreciated. Thanks.
