Add ability to validate schema against corresponding meta-schema

[ekzobrain]

Add an analogue of this AVJ method: https://ajv.js.org/api.html#ajv-validateschema-schema-object-boolean
This method should automatically detect a corresponding meta-schema and run validation against it. Also it should validate that refs are correct (resolvable) and that regular expressions in pattern keywords compile without errors.

Hi Dmitry,

I will catch up on those requests. For the first-part, meta-schema is supported and used in validation. Did you see a different behaviour? Which version are you using?

Note that the library is tested with the official test-suite for all drafts. The results can be seen here
https://github.com/sagold/json-schema-library/actions/runs/16705954493

FYI I know see that for some reason the draft-2020 tests are missing in CI and I will add them shortly

Regards,
Sascha

I did not try it with your validator. I just did not see such case in the docs and in the source code (at the first look). If it is possible somehow then how may I achieve this? At least to validate that my custom JSONSchema is valid (as draft-2020, for example, without checking refs and patterns)?
All fully-featured validation libraries that I saw usually support this via a separate method like "validateSchema()", not via a defaut method for data validation.

Thank you for your feedback! I will the schema option and a global one. The setup for this already exists.

Seems like this comment should belong to another issue :)

Indeed. I was already wondering where the comment went.
