If that is the case, what is 'good logic'? JSON or YAML?

It does not make much difference which format I use. However, I will say 
that I found it a useful discipline to create an xml schema to describe my 
form definition, for two reasons.

Firstly, I was hand-crafting my form definitions initially, and as I added 
features it became unwieldy. Forcing myself to create the schema highlighted 
a lot of anomalies and I ended up with a much cleaner structure as a result.

Secondly, it has picked up a lot of errors in the resulting documents which 
would otherwise have generated hard-to-find runtime exceptions.
