# The pattern's own two scenarios: "the pressure sensed on the couch" and "the electric
# current of the TV". Each feature of interest is a piece of information with no value of
# its own - it names the property (forProperty) and the object that property belongs to
# (isAbout), which is what a sensing process then observes.
