Nicolas,
My tests show that I've fixed that infinite recursion. And, this fix
does not cause a problem with generating the code to validate simple
types (as my previous attempt at fixing it did).
You can find the fixed code here:
https://bitbucket.org/dkuhlman/generateds
The only relevant change, I believe, is in generateDS.py.
Please let me know whether this fixes the issue for you. And, of
course, let me know about any other issues.
Thanks for your help with fixing this.
Dave
