COLLADA FX was introduced in COLLADA 1.4.0 and the 1.4.1 update fixes a
few important issues wrt binding shaders to geometry and rendering
surfaces.

COLLADA FX is a cross/multi-platform definition for effects that
supports many shading languages including: Cg, GLSL, GLSL ES, and soon
(Q1 2007) DirectX/HLSL.

Right! FX Composer 2.0, in beta from NVIDIA, can translate existing
effects and export them as COLLADA FX.
