class RGen::Serializer::QualifiedNameProvider

simple identifier calculation based on qualified names. as a prerequisit, elements must have a local name stored in single attribute attribute_name. there may be classes without the name attribute though and there may be elements without a local name. in both cases the element will have the same qualified name as its container.
