CrossFieldValidatorEntry

Extends:BaseCrossFieldEntry

Cross-field validator entry. Represents a validator that references formValue.* and needs form-level execution.

Supports two types of validators:

  1. Custom validators with cross-field expressions (e.g., formValue.password === formValue.confirmPassword)
  2. Built-in validators with cross-field when conditions (e.g., required when country === 'USA')
