Why not use kwalify with standard YAML to validate my YAML?
Kwalify is a schema validation language that is written in YAML.
It is a descriptive schema language suitable for validating simple YAML.
Kwalify compiles to the strictyaml equivalent but is able to do less. You cannot, for example:
- Plug generated lists that come from outside of the spec (e.g. a list of country code from pycountry).
- Validate parts of the schema which can be either one thing or another - e.g. a list or a single string.
- Plug sub-validators of a document into larger validators.
If your schema is very simple and small, there is no point to using kwalify.
If your schema needs to be shared with a 3rd party - especially a third party using another language, it may be helpful to use it.
If your schema validation requirements are more complicated - e.g. like what is described above - it's best not to use it.
