Nathan,
Very interesting. I must have missed that one somehow. I will definitely
have to take a look for that. If I can find something that works like that I
will write something for it and be happy to share the source.

I like the data structure idea even more because like you said it could
generate any type of structure. I used XML because it has better support
than JSON, but JSON is becoming more popular for sure.
