[spyne] Serializing a model

I am using get_object_as_dict to serialize some data sent to a queue with
the json format.

I have a model which has an xml requirement of:

<some node>
  <node_a ATTR="1st of 2 values"/>
  <node_a ATTR="2nd of 2 values"/>
</some node>

Node_a can only occur zero to two times but must have distinct ATTR values for which
only two exist.

My model is not optimal in that the serialized dict includes 'node_a' values as a list and the
ATTR values as another list so they no longer correlate. I need to know if node_a appears
for which ATTR value it was sent with.

Is their a better way to describe this model while maintaining the nesting structure?

class Foo(ComplexModel):
    __type_name__ = 'Foo'
    _type_info = [
        ('node_b', Mandatory(Unicode(max_len=450))),
        ('node_a', Unicode(max_len=450, max_occurs=2)),
        ('ATTR', XmlAttribute(Unicode(values= ['1st of 2 values', '2nd of 2 values']), attribute_of='node_a'))
