> JBossXB fails to parse an xml file if the xsd contains a choice between an element and a sequence which also contains the element.
> For example, in the follow the choice should allow the option between specifying A and then B, or just B
>                         <choice>
>                                 <sequence>
>                                         <element name="A"/>
>                                         <element name="B"/>
>                                 </sequence>
>                                 <element name="B"/>
>                         </choice>
> But, if an xml file used contains just B, an exception will be thrown saying that B is in the wrong order for the sequence. The expected result would be that it should work since just having B is valid.
> Part of the actual xsd file (http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd) in question:
>                         <choice>
>                                 <sequence>
>                                         <element name="resource-bundle" type="portlet:resource-bundleType"/>
>                                         <element name="portlet-info" type="portlet:portlet-infoType" minOccurs="0"/>
>                                 </sequence>
>                                 <element name="portlet-info" type="portlet:portlet-infoType"/>
>                         </choice>
> Part of the stacktrace thrown when a portlet-info element is declared in an portlet.xml file without resource-bundle:
> Caused by: org.jboss.xb.binding.JBossXBRuntimeException: Requested element {http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd}portlet-info is not allowed in this position in the sequence. The next element should be {http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd}resource-bundle
