so, I can see that you come to
  :Robby :weight [ :inKg [ :inDecimal "14" ] ] .
  :Robby :age [ :inMonth [ :inDecimal "12" ] ] .
  :Jenny :weight [ :inKg [ :inDecimal "12" ] ] .
  :Jenny :age [ :inMonth [ :inDecimal "12" ] ] .
or
  :Robby :weight [ :inKg [ :inOctal "16" ] ] .
  :Robby :age [ :inMonth [ :inDecimal "12" ] ] .
  :Jenny :weight [ :inKg [ :inDecimal "12" ] ] .
  :Jenny :age [ :inMonth [ :inDecimal "12" ] ] .
or

...

or
  :Robby :weight [ :inKg [ :inOctal "16" ] ] .
  :Robby :age [ :inYears [ :inOctal "1" ] ] .
  :Jenny :weight [ :inKg [ :inOctal "14" ] ] .
  :Jenny :age [ :inYears [ :inOctal "1" ] ] .

is that the point?
