Dear Aspose Support Team,
We are currently working on creating PDF/UA-compliant tagged tables using Aspose.PDF for Java.
We have noticed that the Java API does not provide methods such as setHeaders() or setScope() on Cell/TaggedContent, which are required by the PDF/UA standard to associate TD cells with TH headers.
We would like to clarify:
- Is the explicit association of table cells (TD) to table headers (TH) via
Headers or Scope) implemented in Aspose.PDF for Java, or planned for a future release?
- If it is not currently available, is there a recommended workaround to produce PDF/UA-compliant tables using Java?
- Is there a timeline for when this functionality will be available in Java, similar to the .NET API?
Thank you for your guidance.

• Is the PDF/UA compliance feature set in Aspose.PDF for Java currently limited to basic tagging, or are advanced semantic relationships like header-cell associations intentionally excluded?
• Are there any alternative methods in the current Java API to manually create the semantic relationships required for PDF/UA compliance?
• Does the absence of setHeaders() and setScope() methods indicate a gap in the Java API compared to the .NET version, or is there an equivalent approach we’re missing?
• Have other users encountered similar validation errors during PDF/UA compliance testing with Aspose.PDF for Java?
• What specific validation tools or checks are being used that report “Header cell without assigned subcells” - are these part of the standard PDF/UA validation suite?
