As posted to the LinkedIn Accessible PDF group:
"ISO 14289-1 (PDF/UA - universal accessibility) is the authoritative worldwide standard for PDF Accessibility.
The Matterhorn Protocol provides compliance criteria. PAC v2 ... is excellent to the extent that checking can be automated - knowledgeable human inspection is also essential.
The PDF/UA Reference Suite provides best-practice examples - including a form.
The key to removing the ambiguity of conflicting information that you - and all of us - are experiencing is to embrace the ISO standard.
If I produce a form that is demonstrably PDF/UA compliant, and it does not work with a specific tool, then that tool is broken and the tool provider needs to fix it."
