What it does
This interface defines the contract for validation rules applied to EAV (Entity-Attribute-Value) attributes in Magento 2.
Developers use this when creating or managing custom validation rules for product attributes, customer attributes, or any other EAV attributes, ensuring data integrity through key-value pairs representing validation parameters like min/max length or regex patterns.
