Promotion Classes
All promotion classes (product, order, shipping, and bonus) share certain elements that
are defined at the level of the promotion XML element and specified in
promotion.xsd.
The differences between the main promotion classes (product, order, and shipping) are represented as an optional choice of promotion class specific rule elements.
<xsd:choice minOccurs="0" maxOccurs="1">
  <xsd:element name="product-promotion-rule" type="ProductPromotionRule" />
  <xsd:element name="shipping-promotion-rule" type="ShippingPromotionRule" />
  <xsd:element name="order-promotion-rule" type="OrderPromotionRule" />
</xsd:choice>
Excluded product rules are imported and exported with order promotions
using the excluded-products element.
<!-- order promotions -->
<xsd:complexType name="OrderPromotionRule" mixed="false">
  <xsd:sequence>
   <!-- new element-->
    <xsd:element name="excluded-products" type="ProductSpecification" minOccurs="0" maxOccurs="1" />
    <!-- end of new element-->
 ...
    </xsd:sequence>
</xsd:complexType>
The qualifying-products element is supported for shipping and order
promotions.
This is a sample of how an order promotions import and export XML appears:
<promotion campaign-id="Demo Campaign" promotion-id="OP_10_500">
  <enabled-flag>true</enabled-flag>
  <qualifiers>
    <customer-groups/>
  </qualifiers>
  <exclusivity>class</exclusivity>
  <name xml:lang="x-default">10% off orders $500 and up</name>
  <callout-msg xml:lang="x-default">10% off orders $500 and up.</callout-msg>
  <details xml:lang="x-default">10% off orders $500 and up.</details>
    <order-promotion-rule>
<!-- excluded product section -->
      <excluded-products>
         <included-products>
            <condition-group>
              <category-condition catalog-id="mainproduct-catalog">
                <category-id>GiftCerts</category-id>
              </category-condition>
            </condition-group>
         </included-products>
      </excluded-products>
<!-- end of excluded product section -->	
      <discounts condition-type="order-total">
        <discount>
          <threshold>500.0</threshold>
          <percentage>10.0</percentage>
        </discount>
      </discounts>
    </order-promotion-rule>
</promotion>
Note: The 
non-qualifying-products element is deprecated. It is supported on
import but not on export.
