Retrieving OpenXml data without 'with' clause

Question

I have a stored procedure which takes input as XML parameter which converts that into a table.My problem is that I don't to use 'with' clause in select statement when i retrieve data from openXml.
Here My code.
DECLARE @DocHandle int
DECLARE @XmlDocument nvarchar(1000)
SET @XmlDocument = N'<ROOT>
<Customer CustomerID="VINET" ContactName="Paul Henriot">
<Order OrderID="10248" CustomerID="VINET" EmployeeID="5"
OrderDate="1996-07-04T00:00:00">
<OrderDetail ProductID="11" Quantity="12"/>
<OrderDetail ProductID="42" Quantity="10"/>
</Order>
</Customer>
<Customer CustomerID="LILAS" ContactName="Carlos Gonzlez">
<Order OrderID="10283" CustomerID="LILAS" EmployeeID="3"
OrderDate="1996-08-16T00:00:00">
<OrderDetail ProductID="72" Quantity="3"/>
</Order>
</Customer>
</ROOT>'
-- Create an internal representation of the XML document.
EXEC sp_xml_preparedocument @DocHandle OUTPUT, @XmlDocument
-- Execute a SELECT statement using OPENXML rowset provider.
SELECT *
FROM OPENXML (@DocHandle,'/ROOT/Customer',1) WITH (CustomerID varchar(10),---I dont want to use this
EXEC sp_xml_removedocument @DocHandle

Well, the WITH clause is optional. :-) If you remove it, you get a so-called
edge table. Exactly what one would use it for, I have not been able to
figure out.
But you don't need to use OPENXML at all. Here's an example using XQuery
instead:
DECLARE @x xml
SELECT @x =
  N'<Orders>
      <Order OrderID="13000" CustomerID="ALFKI"
             OrderDate="2006-09-20Z" EmployeeID="2">
         <OrderDetails ProductID="76" Price="123" Qty = "10"/>
         <OrderDetails ProductID="16" Price="3.23" Qty = "20"/>
      </Order>
      <Order OrderID="13001" CustomerID="VINET"
             OrderDate="2006-09-20Z" EmployeeID="1">
         <OrderDetails ProductID="12" Price="12.23" Qty = "1"/>
      </Order>
    </Orders>'
SELECT OrderID    = T.Item.value('@OrderID[1]',    'int'),
       CustomerID = T.Item.value('@CustomerID[1]', 'nchar(5)'),
       OrderDate  = T.Item.value('@OrderDate[1]',  'datetime'),
       EmployeeId = T.Item.value('@EmployeeID[1]', 'smallint')
FROM   @x.nodes('/Orders/Order') AS T(Item)
SELECT OrderID    = A.Item.value('@OrderID[1]',    'int'),
       ProductID  = B.Item.value('@ProductID[1]',  'smallint'),
       Price      = B.Item.value('@Price[1]',      'decimal(10,2)'),
       Qty        = B.Item.value('@Qty[1]',        'int')
FROM   @x.nodes('/Orders/Order') AS A(Item)
CROSS  APPLY A.Item.nodes('OrderDetails') AS B (Item)
