HTML updated globally

For screen-reader, we are inside a form, then user can move in form using keyboard and have some information about the actual position with aria and label.

• Replace the label for single question by label to the question.
• Correct the other label in single choice (radio) and multiple choice
• Add help and limesurvey generated help in aria-labelledby or aria-describeddby
• Add roles and aria-labelledby for list of answers (radio, checkbox, text and numeric)
• Add roles and aria-labelledby for arrays of answers (radio, text and checkbox)
• Optionnaly, replace the * usage for mandatory question with the real corresponding string ( for example : “This question is mandatory”).

You can choose to use directly fieldset for list or array, but the aria way are tested in real condition.

Know issue

• For RGAA validation : some totally hidden input didn’t have title or label. This input are not seen or readed in anyway.
• Map question type still not accessible
• Upload question type still not accessible
• Obsolete usage of width for col elements, but this didn’t break a11y
• Obsolete usage of summary for array. In form this part was not used and replaced by usage of aria-describedby and group role for each line.
• DOCTYPE used (DTD XHTML 1.0 Transitional) didn’t allow usage of wai-aria. This break html validation.
• Limesurvey javascript for hide and show conditional question are not fully tested and can not be improved.
