YAML metadata to trigger custom functions that populate missing values

[benbooth493]

Let’s say I have a yaml file with some values that can be empty.
Now say I have a program that reads the yaml and populates some of the values.
The values to populate is determined by a json schema document with additionalProperties: true and with some of the values having a custom property mustPopulate: true.

I am not using the json schema for validation (although I could of course), it’s really just to carry some additional metadata for the yaml file.

Is this pattern possible with Cue? If so, how would I do such a thing?
