<anyAttribute> elementi
<anyAttribute> elementi XML hujjatni sxemada ko‘rsatilmagan atributlar bilan kengaytirish imkonini beradi.
Quyidagi misol "family.xsd" nomli XML sxemasidan olingan fragment. Unda "person" elementining e’loni ko‘rsatilgan. <anyAttribute> elementidan foydalanib, "person" elementiga istalgan miqdordagi atributlarni qo‘shishimiz mumkin:
<xs:element name="person">
<xs:complexType>
<xs:sequence>
<xs:element name="firstname" type="xs:string"/>
<xs:element name="lastname" type="xs:string"/>
</xs:sequence>
<xs:anyAttribute/>
</xs:complexType>
</xs:element>Endi "person" elementini "eyecolor" atributi bilan kengaytirmoqchimiz. Yuqoridagi sxema muallifi hech qanday "eyecolor" atributini e’lon qilmagan bo‘lsa ham, bu holda buni qila olamiz.
"attribute.xsd" nomli ushbu sxema fayliga qarang:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="https://www.w3schools.com"
xmlns="https://www.w3schools.com"
elementFormDefault="qualified">
<xs:attribute name="eyecolor">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern value="blue|brown|green|grey"/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>
</xs:schema>Quyidagi XML fayl ("Myfamily.xml" deb nomlangan) ikki xil sxemadagi komponentlardan foydalanadi: "family.xsd" va "attribute.xsd":
<?xml version="1.0" encoding="UTF-8"?>
<persons xmlns="http://www.microsoft.com"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:SchemaLocation="http://www.microsoft.com family.xsd
https://www.w3schools.com attribute.xsd">
<person eyecolor="green">
<firstname>Hege</firstname>
<lastname>Refsnes</lastname>
</person>
<person eyecolor="blue">
<firstname>Stale</firstname>
<lastname>Refsnes</lastname>
</person>
</persons>Yuqoridagi XML fayl yaroqli (valid), chunki "family.xsd" sxemasi "person" elementiga atribut qo‘shishga ruxsat beradi.
<any> va <anyAttribute> elementlari KENGAYTIRILUVCHAN hujjatlar yaratish uchun ishlatiladi! Ular hujjatlarga asosiy XML sxemasida e’lon qilinmagan qo‘shimcha elementlarni o‘z ichiga olish imkonini beradi.
