6. Dickson Chiu 2004CSIT600b 01-6 Attribute Types ID - key uniquely identifies an element IDREF – points to elements with ID attribute Enumerated attribute types (with default values) <!DOCTYPE bookstore [ <!ATTLIST book shippedBy IDREF #IMPLIED> ]> 2 to 4 days 1 day Java How to Program 3rd edition.

7. Dickson Chiu 2004CSIT600b 01-7 More Attribute Types NMTOKEN / NMTOKENS – name token / tokens, each consists of only letters, digits, periods, periods, underscores, hyphens and colon Conforming element: Attribute need not start with a letter ENTITY – attribute must be a declared entity referring to external unparsed entity Conforming element: ENTITIES – one or more of the above ENTITY Conforming element: (Assume city, boat, train are declared entities.)

8. Dickson Chiu 2004CSIT600b 01-8 XML Schema – Simple Types Elements that do not contain other elements or attributes are of type simpleType. Attributes must be defined last:

11. Dickson Chiu 2004CSIT600b 01-11 XML Schema – Complex Types Elements that contain other elements are of type complexType. List of children of complex type are described by all – must all appear, any order sequence –must all appear according to specified sequence choice – any can appear

12. Dickson Chiu 2004CSIT600b 01-12 Cardinality Cardinality of an element can be represented using attributes minOccurs and maxOccurs (default 1). To represent an optional element, set minOccurs to 0; to indicate there is no maximum number of occurrences, set maxOccurs to “unbounded”. <xsd:element name=“DOB” type=“xsd:date” minOccurs = “0”/> <xsd:element name=“NOK” type=“xsd:string” minOccurs = “0” maxOccurs = “3”/>

13. Dickson Chiu 2004CSIT600b 01-13 References Can use references to elements and attribute definitions. …. If there are many references to STAFFNO, use of references will place definition in one place and improve the maintainability of the schema.

14. Dickson Chiu 2004CSIT600b 01-14 Defining New Types Can also define new data types to create elements and attributes. xsd:simpleTypenamexsd:restrictionbasexsd:totalDigitsvaluexsd:fractionDigitsvaluexsd:restrictionxsd:simpleType xsd:simpleTypenamexsd:restrictionbasexsd:patternvaluexsd:restrictionxsd:simpleType
