@llaine
looks like schema.
a bit a weird design. but interesting problem.
is the list of input_name types known and can they be modeled as separate structs?

otherwise its ok to just parse it as stringAbove.deserialize!InputField[]
and

struct InputField
 bool required;
 string input_name;
 string input_type;
 Validation validation; // or ulong[string]
}

struct Validation
{ int min; int max;}
