However, as of Service Pack 2 (released 2009) Microsoft is not claiming Microsoft Office 2007 compatibility with the ISO OOXML standard.

Open XML Format SDK

 * Microsoft Open XML Format SDK contains a set of managed code libraries to create and manipulate Office Open XML files programmatically. Version 1.0 was released on June 10, 2008 and incorporates the changes made to the Office Open XML specification made during the current ISO/IEC standardization process. Version 2 of the Open XML SDK supports validating Office Open XML documents against the Office Open XML schema, as well as searching in Office Open XML documents. On March 13, 2008 Doug Mahugh, a Senior Product Manager at Microsoft specializing in Office client interoperability and the Open XML file formats confirmed that version 1.0 of the Open XML Format SDK "will definitely be 100% compliant with the final ISO/IEC 29500 spec, including the changes accepted at the BRM". In a ComputerWorld interview from 2008, Doug Mahugh said that "Microsoft would continue to update the SDK to make sure that applications built with it remained compliant with an Open XML standard as changes were made in the future".
