Finally, details on the Custom XML modifications in Word 2007 effective January 10
Last week I posted a rather detailed discussion of the Custom XML modifications that Microsoft was implementing in Word 2007, to comply with a court order that found MS violated a patent by i4i.
Now, at looooooong last, we have technical details about what’s changing in Word 2007 (and therefore in Office 2007). Knowledge Base article 978951 addresses the issue:
Versions of Office Word 2007 that are distributed by Microsoft after January 10, 2010 no longer read the custom XML markup that may be contained within .docx, .docm, or .xml files. The new versions of Office Word 2007 can still open these files, but any custom XML markup is removed. Custom XML markup in Word documents is visible in the Office Word user interface as pink (the default color) tag names surrounding text in a document…
Office Word content controls are not affected by this update. Content controls are a common method of structuring document content and mapping content to the XML data that is stored in a document…
Custom XML markup that is stored within Word 97-2003 document (*.doc) files is not affected by this update.
Ribbon XML and Ribbon Extensibility are not affected by this update. The Word object model is not changed by this update. However some Word object model methods that deal with custom XML markup may return different results.
Sound confusing? Yeah, it is, particularly because MS isn’t changing content controls, but it is zapping manually defined custom XML – but only in Word 2007 docx, docm and XML files.
I have absolutely no idea how these changes map to the patent infringement judgment, and would welcome any enlightening words in the Comments to this post.
