# Captcha/ReCaptcha validators. We override the standard validators from
# plone.formwidget.captcha and plone.formwidget.recaptcha, in order to
# switch between the two. This is necessary, because the zcml registration
# of the CaptchaValidator has to be there, no matter which captcha solution
# is installed, or even when no captcha solution is installed.
