There are cases where more than one Java classes map to the same XML type.
But when we see the same XML type in an incoming document, we only pick
one of those Java classes to unmarshal. This Java class is called 'primary'.
The rest are called 'secondary'.
Currently we lack the proper infrastructure to handle those nicely.
For now, we rely on a hack.
We define secondary mappings first, then primary ones later. GrammarInfo
builds a map from type name to BeanInfo. By defining primary ones later,
those primary bindings will overwrite the secondary ones.
