static QName	ROOT_NAME_FOR_NULL If all we get to serialize is a null, there's no way to figure out expected root name; so let's just default to literal "null".

ROOT_NAME_FOR_NULL

public static final QName ROOT_NAME_FOR_NULL

If all we get to serialize is a null, there's no way to figure out expected root name; so let's just default to literal "null".

_rootNames

protected final transient com.fasterxml.jackson.databind.util.LRUMap<com.fasterxml.jackson.databind.type.ClassKey,QName> _rootNames

For efficient operation, let's try to minimize number of times we need to introspect root element name to use.

Note: changed to transient for 2.3; no point in serializing such state
