Description

Currently the generated Java-clients perform required-validation automatically.
Do you think this makes sense for minLength/maxLength as well, to reject the request on the client side before sending to the server?

For Java the JSR-303 Bean Validation API could be used for this automatically.
For other languages maybe a JSON-schema validation could be used.

Research direction

Start by reviewing how generated Java clients currently perform required validation, then compare the proposed JSR-303 Bean Validation approach with JSON-schema validation for other languages. The issue does not name files or tests; done would require an agreed validation design and implementation scope for minLength/maxLength across the affected client generators.
