> Hi,
> this small GitHub project shows the problem:
> [https://github.com/nkutsche/fop-pdf-ua-table-tagging-issue]
>
> A
> [table|https://github.com/nkutsche/fop-pdf-ua-table-tagging-issue/blob/main/table.fo]
> is rendered to PDF using FOP 2.9 with three different configs. The
> differences are:
> [Config 1: PDF 1.5 is
> requested|https://github.com/nkutsche/fop-pdf-ua-table-tagging-issue/blob/main/config/fop-config.xml].
> [Config 2: PDF 1.5 is requested and PDF/UA-1 mode is
> active.|https://github.com/nkutsche/fop-pdf-ua-table-tagging-issue/blob/main/config/fop-config-ua.xml]
> [Config 3: PDF 1.4 is
> requested.|https://github.com/nkutsche/fop-pdf-ua-table-tagging-issue/blob/main/config/fop-config14.xml]
>
> I analyzed the result PDFs with PAC 2021 - this are the screenshots focosing
> the table footer:
>
> ||Config 1: PDF 1.5||Config 2: PDF/UA-1||Config 3: PDF 1.4||
> |!table.jpg|width=481,height=200!|!table-ua.jpg|width=386,height=200!|!table-14.jpg|width=468,height=200!|

> You see that if the {{PDF/UA-1}} mode is *active* the tagging of
> {{{}TBody{}}}, {{THead}} and {{TFoot}} are lost and the {{TFoot}} row is
> missplaced (at least on my point of view).
> The reason for adding the PDF 1.4 version was, that PDF 1.4 knows only the
> tags {{{}Table{}}}, {{{}TR{}}}, {{TH}} and {{TD}} (See [PDF 1.4
> specification|https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/pdfreference1.4.pdf]
> Table 9.22). With PDF 1.5 {{{}TBody{}}}, {{THead}} and {{TFoot}} was
> introduced (see [PDF 1.5
> specification|https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/pdfreference1.5_v6.pdf]
> Table 10.22).
> *Conclusion:* FOP tags tables in PDF 1.4 style if PDF/UA-1 mode is *active*
> even if PDF 1.5 is generated. If PDF/UA-1 mode is *inactive* it tags tables
> in PDF 1.5 style even if PDF 1.4 is generated.
> Am I correct that this is not the desired behavior? I think we could live
> with the PDF 1.4 style if the table footer wouldn't be on top of the body. On
> my point of view this is also in the PDF 1.4 style wrong.
