dataresponse is an advanced type of response tag that implements
a simple data storage and needs an input tag, such as textline, to work

have the part id and response id added to it.
- type: type of data stored in this response field. It should be one of the types supported by parameter.html
- display: string that will be used to describe
the field when interfacing with humans.
