- Scenario
- Evaluating and improving the accessibility and compliance of interactive XFA PDF forms for assistive technologies.
- Observed behavior
- XFA PDF forms often lack complete accessibility, experiencing missing heading and caption tags, incomplete table headers, inaccessible links, and inconsistent reading orders.
Before modifying your forms, identify the specific accessibility standards required for your organization, such as WCAG 2.0 AA or PDF/UA-1 guidelines, to determine if an XFA format is suitable.
Identify and Remediate XFA Accessibility Barriers
Use this approach to locate common accessibility issues in existing XFA forms and attempt standard PDF remediation where possible.
Because XFA PDF forms are a type of PDF, they should follow the PDF/UA-1 accessibility standards. However, AEM Forms Designer often generates document structures as basic <P> tags, missing crucial semantic elements like <H1>, <H2>, and <Caption>. Complex scripting can also block assistive technologies.
Open your XFA PDF form in a professional PDF editing software and navigate to the Accessibility Tools menu to run a full check.
Open the Tags panel and manually verify if standard heading tags (<H1>, <H2>) and table header tags (<TH>) are properly formatted or missing.
Check the Order panel to ensure the tab order, tag-tree order, and visual reading order are consistent and logical for screen readers.
Click through the document hyperlinks to ensure they are active and verify that any embedded JavaScript does not disrupt keyboard navigation.

Switch to Standard AcroForm PDFs
If advanced XFA features are not strictly necessary, creating an AcroForm PDF offers a more compliant and easily accessible alternative.
Transition to HTML Forms
For forms requiring advanced scripting, dynamic features, or strict WCAG 2.0 AA compliance, web-based HTML forms are highly recommended.
Create Standard PDF Documents Easily with WPS Office
Instead of struggling with complex and inaccessible XFA forms, you can use WPS Office to create standard, lightweight PDFs that are highly compatible, accessible, and easier to manage.
- 1. Create a structured document: Open WPS Writer and start a new document. Use the built-in Styles menu to properly format headings (H1, H2) for better document structure.
- 2. Design the layout: Insert standard tables via the Insert tab, ensuring you clearly define header rows for clear data presentation.
- 3. Export as PDF: Navigate to the Menu, select 'Export to PDF', and choose the standard PDF format to create an easily readable document without proprietary XFA scripts.

Frequently Asked Questions
Why do XFA PDF forms often fail WCAG compliance?
XFA forms typically generate basic paragraph tags (<P>) instead of semantic structure tags like Headings (<H1>, <H2>) and Table Headers (<TH>). This lack of structural tagging, combined with complex embedded scripts and inconsistent reading orders, creates major navigation barriers for screen readers and assistive technologies.
What accessibility standard should PDF forms follow?
PDF forms should ideally adhere to the PDF/UA-1 accessibility standards. While WCAG 2.0 standards are frequently referenced for overall accessibility, PDF/UA provides the specific technical guidelines required to make portable document formats accessible.
Is Level AAA WCAG compliance required for AEM PDF forms?
Generally, no. For most applications and organizations, WCAG 2.0 Levels A and AA are the targeted conformance levels. Satisfying every Level AAA success criterion is often not feasible or recommended as a strict requirement for complex document types like interactive forms.
Are standard AcroForm PDFs more accessible than XFA forms?
Yes, standard AcroForm PDFs are significantly easier to make accessible and remediate. Unlike XFA forms, AcroForms support standard tagging structures and are more universally supported by basic PDF accessibility checking tools and screen readers.
