Indicate when data types are misaligned between source field and OCDS field

During the LIFT Learning Circle someone asked if there was a feature of the template that could flag misaligned data types for given fields. For example if (for some reason) a publisher's database stored a date as a String or Number (UNIX Epoch) and then mapped it to an OCDS field which required "Date" as a data type could there be a way of visually flagging it?

This would be useful to highlight if the publisher or implementer needed to do any additional work. In the example given, they'd need to parse it before putting it into a template which is an extra step.
