Atribut Tavsif
id Ixtiyoriy. Element uchun noyob ID belgilaydi
name Ixtiyoriy. Element uchun nom belgilaydi

  • restriction - cheklash (restriction) orqali hosil qilingan murakkab tiplarni taqiqlaydi
  • #all - barcha hosil qilingan murakkab tiplarni taqiqlaydi

1-misol

Quyidagi misolda murakkab tipga ega "note" nomli element bor:

<xs:element name="note">   <xs:complexType>     <xs:sequence>   <xs:element name="to" type="xs:string"/>   <xs:element name="from" type="xs:string"/>   <xs:element name="heading" type="xs:string"/>   <xs:element name="body" type="xs:string"/>     </xs:sequence>   </xs:complexType> </xs:element>

2-misol

Quyidagi misolda meros olingan tipni uchta qo‘shimcha element (address, city va country) bilan kengaytirish orqali boshqa "personinfo" murakkab tipidan hosil qilingan "fullpersoninfo" murakkab tipi bor:

<xs:element name="employee" type="fullpersoninfo"/> <xs:complexType name="personinfo">   <xs:sequence>     <xs:element name="firstname" type="xs:string"/>     <xs:element name="lastname" type="xs:string"/>   </xs:sequence> </xs:complexType> <xs:complexType name="fullpersoninfo">   <xs:complexContent>     <xs:extension base="personinfo">       <xs:sequence>         <xs:element name="address" type="xs:string"/>         <xs:element name="city" type="xs:string"/>         <xs:element name="country" type="xs:string"/>       </xs:sequence>     </xs:extension>   </xs:complexContent> </xs:complexType>

Yuqoridagi misolda "employee" elementi quyidagi elementlarni ketma-ket tartibda o‘z ichiga olishi kerak: "firstname", "lastname", "address", "city" va "country".
