The IC-ISM XML Schemas will not be included as part of the NIEM 3.0 release. Instead, each of the NIEM structures base types (ObjectType, AssociationType, AugmentationType, and MetadataType, as well as SimpleObjectAttributeGroup) incorporates an anyAttributes element as part of its definition. This wildcard allows any attributes to appear that have the IC-ISM namespace, as well as those having the IC-NTK namespace. This is in line with the recommendations of the developer of the IC Trusted Data Framework, and should support ISM, NTK, and the TDF. Developers that need schemas for these namespaces should download them from an authoritative source.
