What product are you using to transfer your data from the database (ADO,
XML-DBMS, XML SQL Utility for Java, any one of many Web page template
languages, etc.)?

Assuming your data is in a relational database and your schema looks
something like this:

   Table: Products
   Column: ProductID

   Table: Properties
   Columns: ProductID
            codetype
            code

it should be very easy to generate XML that looks like this:

   <order>
      <product>
         <id>1</id>
         <codetype>COLOR</codetype>
         <code>RED</code>
         <codetype>SIZE</codetype>
         <code>LARGE</code>
      </product>
   </order>

or like this:

   <order>
      <product>
         <id>1</id>
         <properties>
            <codetype>COLOR</codetype>
            <code>RED</code>
         </properties>
         <properties>
            <codetype>SIZE</codetype>
            <code>LARGE</code>
         </properties>
      </product>
   </order>
