Expression is an AngularJS Expression, and key(s) are dash-separated combinations of keys and modifiers (one or many, if any. Order does not matter).

 * A validator function will trigger validation on both model and input changes.
 *
 * @example <input ui-validate=" 'myValidatorFunction($value)' ">
 * @example <input ui-validate="{ foo : '$value > anotherModel', bar : 'validateFoo($value)' }">
 * @example <input ui-validate="{ foo : '$value > anotherModel' }" ui-validate-watch=" 'anotherModel' ">
 * @example <input ui-validate="{ foo : '$value > anotherModel', bar : 'validateFoo($value)' }" ui-validate-watch=" { foo : 'anotherModel' } ">
 *
 * @param ui-validate {string|object literal} If strings is passed it should be a scope's function to be used as a validator.
 * If an object literal is passed a key denotes a validation error key while a value should be a validator function.
 * In both cases validator function should take a value to validate as its argument and should return true/false indicating a validation result.
