Renders a property even if the value is blank.
Use this control with the Document Properties Marker Macro (third column) to enforce the rendering of this property in the table even if the value is blank.
Typically rows with empty properties are not shown. This control supports use cases where the property table should render the same amount of rows despite the actual property value. The control may also be used to render a row to assure the reader that the value of the property it actually blank.
