Transmission_color logic

Hello,

I am finding what looks like a conflict in the documentation for transmission_color.

1. in the graph definition we see a coefficient to transmission:
transmission_sheen_mix = transmission * transmission_color * specular_btdf(...) + (1 - transmission) * sheen_layer;
That implies a constant (or textured) color plugged straight as a multiplier.

2. transmission_color: tint due to absorption
transmission_depth: the distance travelled inside the material by white light before its color becomes exactly transmission_color by Beer's law
This implies a depth-based effect. In this case texturing it is not recommendable as it would be a volume effect.

Which one should it be?
