Question on using XMLBeans 1.0.3 ?

I have compiled the example easypo.xsd file and am calling the java
classes that it creates. My question is, I see the main class to call is


    XmlPurchaseOrderDocumentBean newPODoc =
                   XmlPurchaseOrderDocumentBean.Factory.newInstance();
    XmlPurchaseOrderDocumentBean.PurchaseOrder newPO =
                   newPODoc.addNewPurchaseOrder();


but the documention uses:

	PurchaseOrderDocument newPODoc =
		 PurchaseOrderDocument.Factory.newInstance();
    	PurchaseOrder newPO = newPODoc.addNewPurchaseOrder();


Did I invoke the compiler incorrectly ??
