The Markup Compatibility and Extensibility specification contained in part 3 of the IS29500 Open XML specification provides a mechanism for implementers to add and interpret their own markup to an Open XML document while maintaining backward compatibility with existing clients.
In this lab you will learn about Markup Compatibility and Extensibility in the context of the relationship between Microsoft Office 2010 and Microsoft Office 2007. You will see how Office 2010 emits certain MCE constructs to provide up-level constructs for Office 2010 and legacy constructs for Office 2007.
You will then look at how the Open XML SDK 2.0 helps support working with MCE by pre-parsing MCE constructs based on a given Microsoft Office version.
