[Crm-sig] Argument for an Instrument Class (and its property)

Really interesting distinction. When doing pre-digital surveys for maps we used the compass for direction (clearly an instrument, and active?) and bodily calibrated steps to count the meters of distances (clearly part of the human body). Still the results of these measurements were more or less equally (in)accurate and were recorded in a similar way (pencil on transparent paper). 

Can we define by function? Are instruments just anything used for measurements? Neat solution but will lead to quite counter-intuitive claims I fear. 

I am sure the homework will lead to some further questions, hopefully bringing us further. 

Regards,

Øyvind
