Basically, the macro goes through all the endnotes, copies them to the end of the document body, and inserts an incrementally-numbered placeholder in the document body where the endnote used to be and allocates the same number to the endnote content that's been inserted at the end of the document body. The existing endnote numbers are disregarded. The macro then deletes all the Endnotes, before recreating all them from scratch, inserting them at the numbered placeholder locations and transferring the content for each endnote from the end of the document to the Endnote range, thus ensuring they all auto-numbered in the right sequence in both the document body and the Endnote range.
