The InterNational Committee for Information Technology Standards Executive Board, representing the United States, voted 'approve with comments' on adopting Office Open XML as an international standard for office documents. The committee's concerns included:
Source: National Institute of Standards and Technology
- Many key terms in the standard are not yet defined, and concepts are ambiguous ' content type, root namespace, source relationship, comments and real-time data formula, for instance.
- Some of the definitions in the standard are incomplete or incorrect.
- Normative references are needed for cited standards, such as which version of ASCII is required.
- A stronger hash algorithm, such as Secure Hash Algorithm-256, should be required.
- Some informative examples are invalid.
- OOXML uses a proprietary naming scheme rather than ISO/IEC 11179-5 element-naming rules.
- Some requirements are not sufficient to support accessibility requirements of Section 508 of the U.S. Rehabilitation Act.
