DDMS 4.0.1 will likely be out before the ISM files are marked for Public Release.
4.0.1 is a bug fix patch to 4.0 which, although it will share the same XML namespace, will not necessarily be backwards compatible. The ddmsOCType will be removed from the ContactInfoType and the ismocType will be added instead. Because of this irregularity, it would probably be best to support 4.0.1 and NOT 4.0.
Update documentation to 4.0.1. Mention why 4.0 is not supported.
Update codebase to 4.0.1.
Add ismocType validation to the validate() method of the producers.
