XLSB in sintesi
XLSB
XLSB arrived in the post-OOXML era as a pragmatic answer for users who liked modern workbook features but still wanted more binary-oriented storage behavior.
NCX in sintesi
NCX
NCX was defined in the 2005 DAISY and ANSI-NISO talking-book standard, then carried forward into EPUB 2 and later treated as a legacy compatibility feature once EPUB 3 introduced XHTML navigation documents.
