Does annox(https://github.com/highsource/annox) support nested collection object while marshalling/unmarshalling using JAXB?

Question

If I have Collection object class member like ArrayList<ArrayList<Employee>> in some xyz Class, how to marshall this xyz Class object ?

Analogous with 2D, 3D arrays.

Does annox (https://github.com/highsource/annox) support it?

Is it mandatory to have a wrapper class like EmployeeList which will have a member variable as List<Employee> and a wrapper above it like ListOfEmployeeList which will have a member variable as List<EmployeeList>?

Or is it related or equivalent to anyElement of XML.
