JSON representation of a questionnaire

To be visualized, a questionnaire needs to comply to the following XML schema. In JSON, elements with maxMaxOccurs set to unbounded are represented as an array.

For instance, this element in the schema:

<xs:element name="Child" type="ComponentType" minOccurs="0" maxOccurs="unbounded"/>

it will be represented in JSON like this:

{
  "Child": [...]
}

TODO validate from a server perspective

Hence, in JSON, a questionnaire can be represented as follows:
