<xs:annotation>
<xs:documentation>Change Log:
1.1:
schema improvements:
- new complex type GenericReference (used by ModelView and Concept)
- simplified definition of EntityRule and TemplateRule
- definition of applicability attribute changed for ExchangeRequirement and Requirement
- minOccurs changed from 1 to 0 for ModelView.Roots, mvdXML.Templates and Definition.Body
- maxOccurs added to several definitions, mainly for clarification
- definition and use of applicability (was xs:attribute is now xs:simpleType)
- ConceptTemplate.applicableSchema changed to a list of String types
- ConceptRoot.applicableRootEntity now mandatory
schema extensions:
- cardinality attribute of AttributeRule and EntityRule extended to support definition of any min and max settings
- BaseConcept and Override attribute added to Concept
- tags attribute added to Definition
1.0: first published release
informal restrictions:
- ConceptTemplate.Rules shall be restricted to AttributeRules
- Concept.Rules is limited to TemplateRule and AttributeRule
