以下是一個(gè)同時(shí)具有簡(jiǎn)單和復(fù)雜成員類型的例子。它顯示兩層引用。注意"Author"accssor元素的"href"屬性是對(duì)相應(yīng)具有"id"屬性的值的引用。"Address"與之類似。
<e:Book>
<title>My Life and Work</title>
<author href="#Person-1"/>
</e:Book>
<e:Person id="Person-1">
<name>Henry Ford</name>
<address href="#Address-2"/>
</e:Person>
<e:Address id="Address-2">
<email>mailto:henryford@hotmail.com</email>
<web>http://www.henryford.com</web>
</e:Address>
當(dāng)"Person"的值和"Address"的值是multi-reference時(shí)，上面的形式是正確的。如果它們是single-reference，就必須用嵌入的形式，如下所示：
<e:Book>
<title>My Life and Work</title>
<author>
<name>Henry Ford</name>
<address>
<email>mailto:henryford@hotmail.com</email>
<web>http://www.henryford.com</web>
</address>
</author>
</e:Book>
如果添加一個(gè)限制，任意兩個(gè)人都不會(huì)有相同的地址，并且地址可以是街道或Email地址，一本書可以有兩個(gè)作者，編碼如下：
<e:Book>
<title>My Life and Work</title>
<firstauthor href="#Person-1"/>
<secondauthor href="#Person-2"/>
</e:Book>
<e:Person id="Person-1">
<name>Henry Ford</name>
<address xsi:type="m:Electronic-address">
<email>mailto:henryford@hotmail.com</email>
<web>http://www.henryford.com</web>
</address>
</e:Person>
<e:Person id="Person-2">
<name>Samuel Crowther</name>
<address xsi:type="n:Street-address">
<street>Martin Luther King Rd</street>
<city>Raleigh</city>
<state>North Carolina</state>
</address>
</e:Person>
序列化可以包含對(duì)不在同一個(gè)資源的值的引用：
<e:Book>
<title>Paradise Lost</title>
<firstauthor href="http://www.dartmouth.edu/~milton/"/>
</e:Book>
以下是描述上面結(jié)構(gòu)的schema片斷：
<element name="Book" type="tns:Book"/>
<complexType name="Book">
<!-- Either the following group must occur or else the
href attribute must appear, but not both. -->
<sequence minOccurs="0" maxOccurs="1">
<element name="title" type="xsd:string"/>
<element name="firstauthor" type="tns:Person"/>
<element name="secondauthor" type="tns:Person"/>
</sequence>
<attribute name="href" type="uriReference"/>
<attribute name="id" type="ID"/>
<anyAttribute namespace="##other"/>
</complexType>
<element name="Person" base="tns:Person"/>
<complexType name="Person">
<!-- Either the following group must occur or else the
href attribute must appear, but not both. -->
<sequence minOccurs="0" maxOccurs="1">
<element name="name" type="xsd:string"/>
<element name="address" type="tns:Address"/>
</sequence>
<attribute name="href" type="uriReference"/>
<attribute name="id" type="ID"/>
<anyAttribute namespace="##other"/>
</complexType>
<element name="Address" base="tns:Address"/>
<complexType name="Address">
<!-- Either the following group must occur or else the
href attribute must appear, but not both. -->
<sequence minOccurs="0" maxOccurs="1">
<element name="street" type="xsd:string"/>
<element name="city" type="xsd:string"/>
<element name="state" type="xsd:string"/>
</sequence>
<attribute name="href" type="uriReference"/>
<attribute name="id" type="ID"/>
<anyAttribute namespace="##other"/>
</complexType>
