<?xml version="1.0"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:notation name="gif" public="image/gif" system="view.exe"/> <xs:notation name="jpeg" public="image/jpeg" system="view.exe"/> <xs:element name="image"> <xs:complexType> <xs:simpleContent> <xs:attribute name="type"> <xs:simpleType> <xs:restriction base="xs:NOTATION"> <xs:enumeration value="gif"/> <xs:enumeration value="jpeg"/> <xs:restriction> </xs:simpleType> </xs:attribute> </xs:simpleContent> </xs:complexType> </xs:element> </xs:schema>
