Trying to create a schema that will allow a list of four elements under a parent element. At least one of the elements must occur. Each of the four elements should be unique either as different element definitions or with an element definition with an enumerated attribute. This schema frament: <xsd:element name="Style"> <xsd:complexType> <xsd:sequence> <xsd:element name="SizeCategory" minOccurs="1" maxOccurs="4" > <xsd:complexType> <xsd:attribute name="Name" use="required"> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:enumeration value="Missy" /> <xsd:enumeration value="Petite" /> <xsd:enumeration value="Tall" /> <xsd:enumeration value="Womens" /> </xsd:restriction> </xsd:simpleType> </xsd:attribute> </xsd:complexType> </xsd:element> </xsd:sequence> <xsd:attribute name="Number" type="xsd:string" use="required" /> </xsd:complexType> </xsd:element> allows for this XML: <Style Number="51-2301"> <SizeCategory Name="Tall" /> <SizeCategory Name="Petite" /> <SizeCategory Name="Missy" /> <SizeCategory Name="Womens" /> </Style> but I want to modify that schema so that it does not allow this XML: <Style Number="51-2301"> <SizeCategory Name="Missy" /> <SizeCategory Name="Missy" /> </Style> Is there some sort of constraint that can be placed on the size categories to make the Name attribute unique under Style? As an alternative I tried a different approach with this schema fragment: <xsd:element name="Style"> <xsd:complexType> <xsd:all> <xsd:element name="MissyCategory" type="sizeCategory" minOccurs="0" /> <xsd:element name="PetiteCategory" type="sizeCategory" minOccurs="0" /> <xsd:element name="TallCategory" type="sizeCategory" minOccurs="0" /> <xsd:element name="WomensCategory" type="sizeCategory" minOccurs="0" /> </xsd:all> <xsd:attribute name="Number" type="xsd:string" use="required" /> </xsd:complexType> </xsd:element> <xsd:complexType name="sizeCategory" /> which allows for this XML: <Style Number="51-2301"> <TallCategory /> <PetiteCategory /> <WomensCategory /> </Style> but shouldn't allow this XML: <Style Number="51-2301"> </Style> On this version of the Schema if I add minOccurs="1" on the all element would that force at least one sizeCategory element to occur?
