Can I assign a tangent/bonormal vector to a vertex?

I find there are tangent/binormal semantics in Cg. So, can I assign a tangetn/binormal vector to a vertex to use these semantics?

I’m moving this thread to the OpenGL Shading Language forum where it might get an answer it’s definitely too advanced for beginners. Excuse the CG question it was here or the advanced forum.
