Store a byte[] stored in a SQL XML parameter to a varbinary(MAX) field in SQL Server 2005. Can it be done ?

Here's my stored procedure:

set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO

ALTER   PROCEDURE [dbo].[AddPerson]
 @Data AS XML
AS  
 INSERT INTO Persons (name,image_binary)
 SELECT 
  rowWals.value('./@Name', 'varchar(64)') AS [Name],
  rowWals.value('./@ImageBinary', 'varbinary(MAX)') AS [ImageBinary]
 FROM 
  @Data.nodes ('/Data/Names') as b(rowVals)

 SELECT SCOPE_IDENTITY() AS Id

In my schema Name is of type String and ImageBinary is o type byte[].
