VML in sintesi
VML
VML emerged as a 1998 W3C submission backed by Microsoft and partners such as Autodesk, Hewlett-Packard, Macromedia, and Visio, reflecting the moment when web graphics standards were still unsettled.
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.
