<br>
I have a legacy XML schema, and some Haskell data declarations.<br>
I want to map bidirectionally between XML documents and data.<br>
<br>
I absolutely cannot change the schema. I could change the data<br>
declarations, but it would not help much, since I don't think<br>
there is any formĀ of declaring data that would allow me<br>
to derive the transformations generically.<br>
<br>
So, I have a mess of ad-hoc transformations.<br>
What could be done about this?<br>
I think I need "generic with customization".<br>
