PLM — Attributes

the Occurrencies of the Attributes 'role_name', 'role_declaring_type_name' and 'inverse' of the Class 'Location_step' should be coupled as followed: <xs:complexType name="Location_step"> <xs:sequence> <xs:sequence minOccurs="0"> <xs:element name="Role_name" type="xs:string" /> <xs:element name="Role_declaring_type_name" type="xs:string"/> <xs:element name="Inverse" type="xs:boolean" minOccurs="0"/> </xs:sequence> <xs:element name="Predicate" type="Predicate" minOccurs="0" maxOccurs="unbounded"/> <xs:element name="Next_step" type="Location_step" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> because the attributes 'role_declaring_type_name' and 'inverse' make sense only when 'role_name' is set; and a 'role_name' without a 'role_declaring_type' seems problematical.
