According to the last version of spec.templatedata.json, 'required' is optional and defaults to false.

If I have the following JSON:
{
"params": {

		"myparam": {
			"description": "Here should be a description"
		}

}
}

TDG will replace it (when applying without changing anything) with
{
"params": {

		"myparam": {
			"description": "Here should be a description",
			"required": false
		}

},
"description": ""
}

When you’ve edited a big template documentation that didn’t have any 'required' set, that’s really hard to read
