InfoWorld: MS Office XML lags on Mac: January 22, 2004: By Matthew Cooney, Macworld.co.uk: Applications "Microsoft Corp. is readying a new version of Office for Macintosh for release in the first half of 2004 -- but it won't support many of the XML (Extensible Markup Language) features of its Windows cousin, Office 2003.
Although Office 2004 for Macintosh will read and write Excel files saved in XML format, it won't support other XML file formats, including WordML, and won't have any equivalent to Office 2003 features such as XML data binding, "smart" documents, schema libraries and XSL style-sheet support.
Office 2004 will include Word, Excel, Entourage and PowerPoint. A new Professional version will bundle Virtual PC and a Windows XP license.
Microsoft is the largest developer for the Mac other than Apple Computer Inc. Ho says 160 full-time staff work at the Macintosh business unit. Word, Excel and PowerPoint were all originally developed on the Macintosh and later ported to Windows. Microsoft Access and Visio were never available on the Mac, while Entourage is offered on the Macintosh instead of Outlook.
Two new applications released for Office 2003, InfoPath and OneNote, are Windows-only. Microsoft Project for Macintosh is no longer developed."
