+/**
+ * Demonstrats accessing a created DataObject's properties using xPath.
+ *
+ * This 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 code snipets contained
+ * within, and is meant for use with, and reference to the <a
+ * href="http://download.boulder.ibm.com/ibmdl/pub/software/dw/specs/ws-sdo/SDO_Specification_Java_V2.01.pdf"
+ * target="_bank">SDO Specification</a>. <br>
+ * <br>
+ * It is worth noting that the Examples section of the specification, and the
+ * {@link org.apache.tuscany.samples.sdo.specExampleSection.AccessingDataObjectsUsingXPath}
+ * use unpure xpath expression. This sample attempts to demonstrate a more appropiate
+ * subset of xPath operations.<br>
+ * <br>
+ * <b>Usage:</b> <br>
+ * Include the following on your classpath :
+ * codegen-2.2.0-SNAPSHOT.jar,codegen-ecore-2.2.0-SNAPSHOT.jar,common-2.2.0-SNAPSHOT.jar,ecore-2.2.0-SNAPSHOT.jar,ecore-change-2.2.0-SNAPSHOT.jar,ecore-xmi-2.2.0-SNAPSHOT.jar,sdo-api-SNAPSHOT.jar,tuscany-sdo-impl-SNAPSHOT.jar,xsd-2.2.0-SNAPSHOT.jar,sdo-samples-standAlone-1.0-SNAPSHOT.jar
