"The page Vector sends to Numeric Expression, but that one dismiss any details
about DOT_ITEM by sending back to Vector / Colour Pages, none of which cover the
subject."

I think that addressing the following ought to explicitly, clearly and
unambiguously describe what the values are as well as show examples of their
usage.

(I'm assuming that Vector.gray = (Vector.red + Vector.green + Vector.blue)/3
and that would be a helpful tidbit in the docs as well. )

#version 3.7;
global_settings {assumed_gamma 1.0}
#include "debug.inc"
  Set_Debug (true)

#declare Vector = <1, 2, 3, 4, 5>;

#debug concat( "Vector.x =        ", str(Vector.x, 3, 0), "\n")
#debug concat( "Vector.red =      ", str(Vector.red, 3, 0), "\n")
#debug concat( "Vector.u =        ", str(Vector.u, 3, 0), "\n\n")

#debug concat( "Vector.y =        ", str(Vector.y, 3, 0), "\n")
#debug concat( "Vector.green =    ", str(Vector.green, 3, 0), "\n")
#debug concat( "Vector.v =        ", str(Vector.v, 3, 0), "\n\n")

#debug concat( "Vector.blue =     ", str(Vector.blue, 3, 0), "\n")
#debug concat( "Vector.z =        ", str(Vector.z, 3, 0), "\n\n")

#debug concat( "Vector.t =        ", str(Vector.t, 3, 0), "\n")
#debug concat( "Vector.filter =   ", str(Vector.filter, 3, 0), "\n\n")

#debug concat( "Vector.transmit = ", str(Vector.transmit, 3, 0), "\n\n")

#debug concat( "Vector.gray = ", str(Vector.gray, 3, 0), "\n\n")
