Fascinating.  In high-level conceptual terms, I have always considered an
occurrence to be a form of observation, not the other way around.  This is
because an occurrence records the presence or absence of an individual of a
species at a particular place and time.  An observation is a record of any
type of measurement within any context, and so might include, for example,
the measurement of the size of an organism at a location and time.  This
observation can then be used to infer that the organism was present at that
place and time, and therefore that we can say it occurred there as well.
