Data Type: Which type of data this element is, e.g. String, Float, File location.
Size: If applicable, the character limit of this element
Required: This column displays whether the element is Required for valid submissions, Recommended for valid submissions, Conditional on other elements, or Optional
Description: A basic description
Value Range: Which values can appear validly in this element (case sensitive for strings)
Notes: Expanded description or notes on coding of values
