# 3.1.16

## Upgrading

FormField validation messages generated by the `Validator` class will now be automatically XML
encoded before being rendered alongside an invalid field.

If a validation message in a custom `Validator` instance should be rendered as literal HTML,
then the $message parameter for `Validator::validationError` should be passed as an instance
of `HTMLText`

For example:


	:::php
	class MyCustomValidator extends Validator {
		public function php($data) { 
			$this->validationError(
				'EmailAddress',
				DBField::create_field('HTMLText', "Invalid email. Please sign up at <a href='signup'>this page</a>")
			);
		}
	}
