XML Schema to Java - XSD Choice

In a previous blog post I wrote about how to map to the choice structure in XML schema when starting from classes.  An astute reader tried generating an object model from that schema and noticed that the JAXB implementation generated something different than expected.  In this post I'll explain the difference.

JAXB and XSD Choice: @XmlElements

XML Schema has the concept of a choice element.  The choice element indicates that one of the elements defined within the choice may occur at this point in the XML document.  In this example I will demonstrate how easily this can be mapped using JAXB.
