/**
* Demonstrates programmatically creating a DataObject and generating an XML String.
* <br>
* The following sample is from the <a href="http://incubator.apache.org/tuscany"
* target="_blank"> Apache Tuscany</a> project. It was written to help users
* understand and experiement with SDO. It is based upon example code contained
* within, and is meant for use with, and reference to the <a
* href="http://www.osoa.org/download/attachments/791/SDO_Specification_Java_V2.01.pdf?version=1"
* target="_bank">SDO Specification</a>. In general this sample attempts to use the
* code and comments contained within the specification, exceptions to this are noted
* in comments.<br>
* <br>
* Specifically this sample is based upon the 'Creating XML from DataObjects' example
* from the SDO specification's Examples section. <br>
* <br>
* Uses previously defined model
* {@link org.apache.tuscany.samples.sdo.SdoSampleConstants#PO_XSD_RESOURCE} to
* define types then generates a purchase order DataObject and persists to
* {@link org.apache.tuscany.samples.sdo.SdoSampleConstants#PO_XML_GENERATED}
* <br><br>
* <b>Usage:</b> <br>
* This sample can easily be run from within Eclipse as a Java Application if tuscany or
* the sample-sdo project is imported into Eclipse as an existing project.
* <br><br>
* If executing as a standalone application please do the following:
* <br>
* <UL>
* <LI>Include the following jar files on your classpath :
* <UL>
* <LI>SDO API and Tuscany Implementation
* <UL>
* <LI>sdo-api-{version}.jar - SDO API
* <LI>tuscany-sdo-impl-{version}.jar - Tuscany SDO implementation
* </UL>
* </LI>
* <LI>EMF dependencies.
