There's a bunch of different tools for YAML validation indeed. "kwalify" was
one, I think. With a name like that .. :) Unfortunately, lots of the tools are
also unmaintained, as I found out when I went looking recently.
JSON-schema claims, though, to be maintained and applies to YAML and beyond
(for those sensible cases where your YAML is a representation of JSON, and not
the edge cases of what YAML can do).
For Calamares, which is chock-full of simple YAML files, I ended up bodging a
tool together in Python where most of the code ends up being validation logic,
followed by one call to the Python library `jsonschema`. There's probably
other ready-to-go tools like it.
A typical schema file for JSON-schema can be represented in YAML as well
(because YAML is JSON, or something). Here's one, which has some enums,
handles a list, and also contains string and boolean settings:

(From a JSON-schema perspective) You might periodically generate a schema type
that checks the repository-re, for the simple case of |-separated full
repository names. Personally I'd be more inclined to follow Albert's original
question, and change the tool not to eat a RE but a YAML list-of-repo-names.
