It kind of depends on where the Map is used. If it's used inside a JAXB
bean, it will work fine. When JAXB is processing the bean, it recognizes the
map and will create a "generic" schema for it. (not pretty, but works).
The schema kind of sucks which is why the @XmlJavaTypeAdapter is strongly
recommended.
However, you cannot create a JAXB context that will marshall/unmarshall a Map.
It will throw a "interfaces are not allowed" type of exception. Thus, Maps
aren't really usable for top level types.
Thus, it's a kind of "half supportable" type thing.
