I am trying to create a tagged PDF form to ensure its accessibility. I would like to know which element type I should assign to a field label. In other words, let's say I have a form I created in Word and then saved as a PDF, and the first line looks like this:
There is a Last Name field located just above the line, and it is tagged "Form". Now, how should I tag the words "Last Name"? I don't see an option like "Field Label" as an element, but "Paragraph" doesn't seem appropriate.
As a general rule I look to the PDF/UA Reference Suite (http://www.pdfa.org/publication/pdfua-reference-suite/) for best practice tagging examples. Document 10 in the suite is a form. It uses this approach:
Don't forget to include a Tooltip in the form field properties.
