Microsoft Office Open XML Formats
The popular wisdom is that it takes Microsoft until Release 3 of anything to get it right; but the early word on the new Office XML format makes Release 2 look pretty good. Reading between the lines, the big news is, first, that the default file-save format is XML and, second, that the XML coverage is complete
Mac Office 12 will support the new file formats as well. Also, as with Win Office, we'll be producing converters for Office X and Office 2004.…For us in Mac BU, this represents an enormous undertaking on two fronts. Win Office is already well ahead of Mac Office in terms of support for XML, and the state of XML parsing on Panther is, well, less than desirable (among other things, the version of libXML that ships on Panther doesn't support SAX 2.0's namespace changes).
