MOXy DynamicJAXBContext XML namespace attributes

[robinroos]

I am migrating a use-case from XML -> SaticJAXB -> MongoDocument to XML -> DynamicJAXB -> MongoDocument

DynamicJAXBContext dynamicContext = DynamicJAXBContextFactory.createContextFromXSD(xmlSchema, entityResolver, classLoader, properties);
JAXBUnmarshaller unmarshaller = dynamicContext.createUnmarshaller();
JAXBElement root = (JAXBElement) unmarshaller.unmarshal(xml);

In order to avoid information loss, so the same XML can be reconstitutes from the JSON/BSON data in mongodb, it is necessary that XML attributes also are persisted. In my case these are typically "xsi:noNamespaceSchemaLocation" and "xmlns:xsi".

At present those are not present in the Map<String, DynamicEntityImpl.PropertyWrapper> propertiesMap of the DynamicEntityImpl which is the value() of the JAXBElement representing the root node, nor are they available on the JAXBElement itself.

It would be most helpful if these XML attributes were added to the propertiesMap of the root node, perhaps governed by a new configuration property XML_INCLUDE_NAMESPACE_ATTRIBUTES.

FYI - I am finding MOXy to be extremely promising for this use-case.
