We've published today a new set of Open XML implementation notes. The ECMA-376 Implementation Notes helps developers to understand low-level details of the Open XML implementation. The notes also include information that will help ISO update the standard over time, and some other general information to cover some scenarios that are not covered in detail by the SPEC.
The notes are definitely a great resource for all us who work with the Open XML SDK 1.0 and 2.0 and are looking for detailed documentation and guidance. I know lots of devs out there are creating document assembly solutions and the notes help you understand fine details of the implementation. Say you are working with WordprocessingML and want to learn about paragraphs, tables, footers, document parts, or mail merge. If you don't know the SPEC by heart (like most of us J), and want to learn more about the implementation details, you can always check out the implementation notes.
