Is it correct to define both pattern and format for type string property? about understanding-json-schema

[Relequestual]

There are many situations that can, and legitimately so, result in a schema for which it's impossible for any data to be valid against.

This is expected. There may be conflicts. One keyword doesn't take any precedence (in terms of preventing another from being used, in your example) than another.

It's also worth noting, that by default, format "does nothing", and implementations MAY choose to provide another layer of validation. You can't expect others using your schema to rely on format.

Thanks for the quick reply!

Understood, so from what I gathered it's up to corresponding implementations to understand what they should do in these cases given schema. And the schema I have mentioned is correct and valid.

Let me know if anything is wrong with what I mentioned.

That's correct. Closing issue as question has been answered.
