tagged pdf: how to do it efficient? (ALD 12.3.1.0)

Good morning,

it is heavy task to shift our structured data into the restrictions of pdf/UA.

With the simple blue code most of it could be achieved by

<?pdftagstart "H1">Heading 1<?pdftagend "H1">

<?pdftagstart "P">Text Ceterum censeo<?pdftagend "P">

<?pdftagstart "P">Text Ceterum censeo<?pdftagend "P">

<?pdftagstart "P">Text Ceterum censeo<?pdftagend "P">

Even Artifact could be tagged easily.

Having Footnotes or even Endnotes is where the creation of pdf (ALD 12.3.1.0) get disrupted.

There could be different ways of tranfering text from a visual layer, like pdf was intitially, to the structured demands, which are imposed on us via pdf/UA.

My favourite would be to shift the tag of the Footnote (and even the Endnote) straight behind the Footnote-Reference in the structured text. 

But how?

• by tags, like <Note> (and Reference),
• by <alttext> (or any kind of form) or
• by assets (in a subfolder with the plain footnotes/endnotes as a txt-file).

Any suggestions?

A few snippets of code would be appreciated by me (and the community).

Best regards,

Jean

PS: I had a deeper look into the help, the pdf-Files and some sample documents. 

There is one file, PDF_Tagging_Sampler.3d, with the heading Footnotes on page 8, but just the heading and not a single footnote or hint how to tag footnotes.
