The anchor is an inline atom, the note text a block in the one noteSection at the document end; a sync plugin keeps notes in anchor order, renumbers them per class and drops the ones whose anchor is gone. Numbering, indent, size and separator defaults are LibreOffice's, read out of a document it saved. Endnotes still render in flow at the document end — lifting a footnote to the foot of its page is the next step.
