Hi

I have follwing XSD which contains three elements i.e., RID, BID and KID of which only one of
them should present and remaing are optional.
Could any body please tell me how to achieve this

<xs:element name="CustomerCode">
<xs:complexType>
<xs:sequence>
<xs:element name="RID">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern value="[A-Z0-9]{15}" />
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="BID">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern value="[A-Z0-9]{15}" />
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="KD">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern value="[A-Z0-9]{15}" />
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>


Thanks in advance
