So, splitting the solution into separate archival and unarchiving into 2 
sections, where the unsupported classes are handled separately is the ugly but

Sort of a wrapper for archiving and unarchiving to handle NSParagraphStyle 
storage and rebuilding?

That’s my first inclination, but thought I’d ask for the sake of discussion.
