I'm not a big fan of XML or XSD or XLS either because the documentation is poor, or my understandig of the documentation is poor.

Either way I have a problem. Part of a schema that a 3rd part has supplied is this

xml Code:
 
<xs:element name="DeliveredToAE" maxOccurs="unbounded">
	<xs:complexType>
		<xs:sequence>
			<xs:element name="DeliveredToOperator">
				<xs:complexType>
					<xs:sequence>
						<xs:element name="AEApprovalNo" type="aeApprovalNoType"/>
						<xs:element name="OperatorName">
							<xs:simpleType>
								<xs:restriction base="xs:string">
									<xs:maxLength value="250"/>
								</xs:restriction>
							</xs:simpleType>
						</xs:element>
					</xs:sequence>
				</xs:complexType>
			</xs:element>
			<xs:element name="Return" type="TonnageReturnType" maxOccurs="26"/>
		</xs:sequence>
	</xs:complexType>
	<xs:unique name="uniqueCategoryObligationDeliveredToAE">
		<xs:selector xpath="Return"/>
		<xs:field xpath="CategoryName"/>
		<xs:field xpath="ObligationType"/>
	</xs:unique>
</xs:element>


When I have relevant records I have no problem in creating the valid XML that validates agaisnt this part of the schema.

The validation fails when I have no data to make any XML elements of <DeliveredToAE>.

If i leave it out then the validation fails saying that it was expected
If I put an empty one in then I get an error saying that it is incomplete

Assuming I have no data for "DeliveredToAE" and given this schema, what would be the valid XML to put in?
