At the top of the illustration is the native format message. The native format message takes the following format:

message ::= <action> <model> <price>

Below this is the native format message payload data, which takes the following format:

"*UPDATE_PRICE* 2468 |199.99|"

Three arrows are used to show the relationship between the native format message and the native format message payload data:

• An arrow points from <action> to *UPDATE_PRICE*
• An arrow points from <model> to 2468
• An arrow points from <price> to |199.99|

Below this is D3L file price.xml syntax:

<?xml version="1.0" encoding="US-ASCII"?>

<!DOCTYPE message SYSTEM "d3l.dtd">

<message name="changePrice" object="Product" type="priceCommand">

<struct id="priceCommand">

<field name="action"><limstring delimiter="*"/> </field>

<field name="model"><limstring delimiter=" "/> </field>

<field name="price"><limstring delimiter="|"/> </field>

</struct>

Three arrows are used to show the relationship between the native format message payload data and the D3L file price.xml syntax:

• An arrow points to <field name="action"><limstring delimiter="*"/> from *UPDATE_PRICE*
• An arrow points to <field name="model"><limstring delimiter=" "/> from 2468
• An arrow points to <field name="price"><limstring delimiter="|"/> from |199.99|
