I am try to prefill an adaptive form which has the data model created out of json schema. I have gone through the below url to understand how the prefill woks in adaptive forms.
Adobe Experience Manager Help | Prefill adaptive form fields https://helpx.adobe.com/experience-manager/6-2/forms/using/prepopulate-adaptive-form-fields.html#mai...
But in this example I see the form created out of an XML schema and the prefill data is also in form of xml with bound and unbound tags. In the sameway can I configure json with bound and unbound tags to prefill the form or is it mandatory to have an xml ?
