Hi, I'm looking at the v1.1 schemas you have just released, and have noticed that you have removed restrictions on the usage of elements. For example, <xs:element name="objectIdentifierType" minOccurs="1" maxOccurs="1" type="xs:string"> has become <xs:element name="objectIdentifierType" type="xs:string"> As the 'repeatability' and 'obligation' of these elements are specified in the data dictionary, it seemed to make sense that this also be included in the schema itself. Can you please indicate why this was removed?
