Schema: ability to represent union types?

[DeaconDesperado]

Consider the following KDL nodes: semantically they are named colors, and they can be defined using:

• a hex string
• a 1 digit 256 color code
• a 3 digit Truecolor code

colorX "#79646A"
colorY 16
colorZ 255 184 108

Assuming the node name represents the color name, how could one validate for the union type of string | number | (number, number, number) using the schema definition?

There's no support for this right now, but now's a good time to spec it out. Do you want to give it a shot? I think you'd need to add a new union node that's basically identical to the node, but can specify different "shapes" of that node. I say union, because enum is already taken by the "these specific values" concept.

Thanks! I can make an attempt at it!
