Cell-comment support on a
TXLSXWorksheet. Each
entry attaches an author plus a free-text body to a cell. SaveAs emits
xl/commentsN.xml with a deduplicated author list and a
companion
xl/drawings/vmlDrawingN.vml så att Excel kan rendera kommentarsbubblorna; Open läser kommentarernas XML tillbaka till samlingen. Deklarerad i
lxHandleX
