 #TODO: find a good tool to make the validation on request
 # https://achecker.ca/documentation/web_service_api.php - API usage depends on user account creation
 # webaim.org - API's not gratis
 
-# While we don't have a validator on request, let's find out if a known violation still exists
-## 20/05/2018: - several images without an alt attribute:
-## 28/02/2019: the missing alts case is no longer a problem, but to comply with WCAG the XHTML also needs to be valid...
-##             https://validator.w3.org/nu/?doc=https%3A%2F%2Fwww.iefp.pt%2F
-##             tidy is a great validator, but isn't catching the errors on this
-##             page as errors, even if it shows them as warnings... let's be hacky and pay
-##             attention only on the current use case:
-## 03/04/2019: XHTML is now valid, but there are empty headers now, in violation of levels A and AA
