1 Bug Description
=================

  When an `ODT' file with `Nested Footnote Definition' is imported in to
  LO 25.2 (dtd. 2024-Nov-23 03:10) it results in Data Loss. There are
  two issues:

  - The user has to be INFORMED that the LO encountered `Nested
      Footnotes' during import and it HAS MOST DEFINITELY _ignored_ some
      `Footnote Definitions'.

    IOW, LO has to ALERT the user about what it did to the user behind
    his back.

  - Instead of going with 'Data Loss'-on-Import, LO can rewrite the
    input XML to an agreeable equivalent.  See attachment for what I
    mean here.


  This bug is a follow up to

  ['Bug 163974 - (May be ODF-spec related) Nested Footnotes: LO reports
  `Read Error` but `ODFValidator` is quite happy']

1.1 What ODF spec says about 'Nested Footnotes'
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

        <https://docs.oasis-open.org/office/OpenDocument/v1.4/OpenDocument-v1.4-part3-schema.html#element-text_note-body>

        > Note: The schema allows for the inclusion of <text:note>
        > elements as a descendant of a child of the
        > <text:note-body> element. While this may be reasonable
        > for note types, it is not reasonable for footnotes and
        > endnotes.  Conforming consumers need not support notes
        > inside notes.
