EMF in sintesi
EMF
Microsoft deprecated WMF in favour of EMF due to WMF's issues with device independence. EMF was later extended with EMF+ to support GDI+ drawing operations.
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.
