"replace value of" and enum

I've created XML SCHEMA COLLECTION AS
<?xml version="1.0" encoding="utf-8"?>
<xs:schema elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Order" nillable="true" type="Order" />
<xs:complexType name="Order">
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="1" name="Status"
type="OrderStatus" />
</xs:sequence>
</xs:complexType>
<xs:simpleType name="OrderStatus">
<xs:restriction base="xs:string">
<xs:enumeration value="New" />
<xs:enumeration value="Pending" />
<xs:enumeration value="Complete" />
</xs:restriction>
</xs:simpleType>
</xs:schema>
Now I'd like to update OrderStatus:
UPDATE Orders
SET OrderXml.modify('replace value of (/Order[1]/Status[1]) with "Expired"')
I get:
Msg 2247, Level 16, State 1, Procedure Orders_Select
XQuery [dbo.Orders.OrderXml.modify()]: The value is of type "xs:string",
which is not a subtype of the expected type "OrderStatus".
The below does not work either:
UPDATE Orders
SET OrderXml.modify('replace value of (/Order[1]/Status[1]) with
OrderStatus("Expired")')
How do I make this work?
Thanks
Never mind, ("Expired" cast as OrderStatus) does the trick.
