Hi Shalika, This particular validation functionality has been partially implemented (Without UI support) across various customer implementations.
However, before implementing this feature, we should be able to consider having options to use JSON schema validation options at the resource level or on a global level. I have already done a custom handler implementation for JSON validation by using the json*-schema-validator *library which is being used with the EI's Validator mediator. AFAIK Lahiru implemented a comprehensive JSON schema validation library.
