Camel Bindy Fixed Length with Complex Structures

Question

I am trying to understand whether bindy is able to manage some of the complex structures I am being asked to use to model a fixed length row.

I have a model that has nested classes and one of the nested classes its self references a class that is linked at the parent level (which is entirely possible, its similar I guess to normalisation). So, for example you might have a class structure

`

class-A
 -> String
 -> class-b 
 -> class-c
    -> String
    -> class-b
    -> String
 -> class-d
 -> String
 -> String

`

In the above structure, class-b models a set of data that is present as an attribute on both class-A and class-c. It seems to me that this is impossible because "class-b" would need to have definitions for 2 different positions in the structure. Is this correct, is this a limitation on the Bindy format?

thanks Paul
