The exact Java representation of StatusDetailType need not have a
List<Object> since <any/> does not have maxOccurs /= 1.
Answer #1:
In the Java code, there is no explicit information about the XML element tag
to use for an element of schema type
MissingAttributeDetailType. You must have prepared a document by
StatusDetailType sd = ...;
MissingAttributeDetailType mad = ...;
sd.getContent().add( mad );
Thus, the only information for the marshaller about the XML element to take
the place of the <any/> wildcard is object mad's class, which happens to be
MissingAttributeDetailType.
To get the correct XML element tag, you must create an object of class
JAXBElement<MissingAttributeDetailType> which contains an Object field
"value" (set to a MissingAttributeDetailType, defining all the children of
the element), and a
javax.xml.namespace.QName field "name" defining the tag's namespace and
local name.
The easiest way for obtaining code creating the JAXBElement<?> would be to
xjc-compile the schema with the complex types and an additional
<xs:element name="MissingAttributeDetail"
type="MissingAttributeDetailType"/>
The ObjectFactory.java contains a suitable method
createMissingAttributeDetail(...)
Or see
https://jaxb.dev.java.net/tutorial/section_4_5-Calling-marshal.html
the method wrap to create an arbitrary JAXBElement.
Answer #2:
Then, you won't need @XmlRootElement for class MissingAttributeDetailType
any more, because, being wrapped in an JAXBElement object, it won't be a
class for a "root" element any more.
