‘Note’is the inline-level Structure Element for explanatory text such as a footnote or an endnote. AH Formatter automatically tags fo:footnote-body as ‘Note’. However, ‘Note’ is defined in PDF 1.7 as an inline-level Structure Element, whereas an fo:footnote-body contains block-level FOs. As such, PDF/UA that is generated from XSL-FO that contains footnotes will be flagged by a PDF/UA checker.

Structure Elements for notes have been revised in PDF 2.0 []. PDF 2.0 has removed‘Note’ and added ‘FENote’, which is allowed at grouping, block, and inline levels.
