getFields response

We found a few instances of "strange" json schema fragments ( for the operation getFields ), like the following

"NationalIds": {

"title": "NationalIds",

"type": "object",

"properties": {

"Number": {

"type": "string",

"description": "(10-digit Australian Medicare number)"

},

"Type": {

"type": "string",

"value": "health"

}

},

"required": [

"health"

]

}


a property "health" is required but not defined.
