    tests: Label parts with decimals, not roman numerals
    
    dblatex (via gtkdoc-mkpdf) warns that labels must be integers:
    
        Warning: only an integer in @label can be processed: 'I'
        Warning: only an integer in @label can be processed: 'II'
        Warning: only an integer in @label can be processed: 'III'
    
    Make the labels decimal to placate dblatex. I'm not sure this is
    actually the best solution, though.
