No. Basically, a top level element references another element and then
the element references another child element and so on. Finally, the
deepest element references an attribute group that in turn references
another attribute group which in turn also references another
attribute group (all are independent of each other). The attributes
from the last attribute group are not reflected in the generated proxy
class. However, if I move the last referenced attribute group to one
level above, then the proxy class correctly shows all the attributes
as public properties.
