Alle, die sich selber eine Meinung zu dem sehr umstrittenen "Open XML" bilden wollen, können das kostenlose eBook "Open XML – The markup explained" von Wouter van Vugt jetzt bei Microsoft downloaden. Er selber schreibt:

In this book you will be provided a detailed overview of the three major markup languages in Open XML. This book is written for those who have a basic understanding of XML or HTML. If you are a software architect or developer who needs to build document-centric solutions you can learn about how to build your value-added solutions based on the Open XML platform. Those new to document markup languages as well as those more experienced in document markup but new to Open XML will benefit from this book.

Ich habe es mal überflogen, es scheint sich gut zu lesen.
