Example 1
The following example shows a gif and a jpeg notation using a viewer application, view.exe:
<?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>
The "image" element in a document could look like this:
<image type="gif"></image>
<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>
The "image" element in a document could look like this:
<image type="gif"></image>
