== An XML Schema Document Using Named Type Definitions==



<source lang="xml">
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
targetNamespace="http://www.wbex.ru/namespaces/pub"
xmlns="http://www.wbex.ru/namespaces/pub">
<xsd:simpleType name="isbnType">
<xsd:restriction base="xsd:string">
<xsd:pattern value="[0-9]{10}" />
</xsd:restriction>
</xsd:simpleType>
<xsd:complexType name="pubType">
<xsd:sequence>
<xsd:element ref="book" />
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="bookType">
<xsd:sequence>
<xsd:element ref="title" />
<xsd:element ref="author" />

<xsd:element name="author" type="xsd:string" />
<xsd:element name="description" type="xsd:string" />
</xsd:schema></source>

== extend the complex type that we have defined, creating new types for Customer and Employee:==



<source lang="xml">
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.wbex.ru" xmlns="http://www.wbex.ru"
elementFormDefault="qualified">
<xs:complexType name = "PersonType">
<xs:sequence>
<xs:element name = "Name" type = "xs:string" />
<xs:element name = "Address" type = "xs:string" />
<xs:element name = "Econtact" type = "xs:string" />
</xs:sequence>
</xs:complexType>

<xs:element name = "Customer">
<xs:complexType>
<xs:complexContent>
<xs:extension base = "PersonType">
<xs:sequence>
<xs:element name = "AccountDetails" type = "xs:string" />
</xs:sequence>
<xs:attribute name = "customerID" type = "xs:string" />
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:element>

<xs:element name = "Employee">
<xs:complexType>
<xs:complexContent>
<xs:extension base = "PersonType">
<xs:sequence>
<xs:element name = "JobRole" type = "xs:string" />
<xs:element name = "Department" type = "xs:string" />
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:element>
</xs:schema></source>

== how XML Schema allows us to re-use names, and give them different content models.==



<source lang="xml">
<?xml version = "1.0" ?>
<xs:schema xmlns:xs = "http://www.w3.org/2001/XMLSchema"
targetNamespace = "http://www.wbex.ru/books"
xmlns:book = "http://www.wbex.ru/books"
elementFormDefault = "qualified">

<xs:element name = "Book">
<xs:complexType>
<xs:sequence>
<xs:element name="TitleInformation" type = "book:TitleInformationType" />
<xs:element name="Chapter" type = "book:ChapterType" minOccurs = "1" maxOccurs = "unbounded" />
</xs:sequence>
</xs:complexType>
</xs:element>

<xs:complexType name = "TitleInformationType">
<xs:sequence>
<xs:element name = "Title" type = "xs:string" />
<xs:element name = "Author" type = "xs:string" />
<xs:element name = "Publisher" type = "xs:string" />
</xs:sequence>
</xs:complexType>

<xs:complexType name = "ChapterType">
<xs:sequence>
<xs:element name = "Title">
<xs:complexType>
<xs:simpleContent>
<xs:extension base = "xs:string">
<xs:attribute name = "indexMark" type = "xs:ID" use = "required" />
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name = "chapterNumber" type = "xs:integer" />
</xs:complexType>

</xs:schema></source>

== Re-use in Text-only Element Content Models==



<source lang="xml">
File: Schema.xsd
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.wbex.ru" xmlns="http://www.wbex.ru"
elementFormDefault="qualified">
<xs:element name = "AccountReviewYear">
<xs:simpleType>
<xs:restriction base = "xs:gYear">
<xs:pattern value="200[1-9]"/>
</xs:restriction>
</xs:simpleType>
</xs:element>

<xs:simpleType name = "fixedLengthFieldType">
<xs:restriction base = "xs:string">
<xs:minLength value = "0" />
<xs:maxLength value = "256" />
</xs:restriction>
</xs:simpleType>

<xs:element name = "ClientName" type = "fixedLengthFieldType" />
<xs:element name = "BranchName" type = "fixedLengthFieldType" />
</xs:schema></source>

== Salami Slice design Define global element declarations that are later referenced.==



<source lang="xml">
<xsd:element name="title" type="xsd:string"/>
<xsd:element name="author" type="xsd:string"/>
<xsd:element name="description" type="xsd:string"/>
<xsd:element name="Book">
<xsd:complexType>
<xsd:sequence>
<xsd:element ref="title"/>
<xsd:element ref="author"/>
<xsd:element ref="description"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element></source>

== Schema reuse==



<source lang="xml">

<?xml version = "1.0" ?>
