A Signal K path observation carried in a log entry, in the flattened delta
pathvalue form used by delta updates and the History API responses: values
are Signal K SI and follow the specification's value shapes. Beyond path
and value the pathvalue may carry the delta value members $source and
timestamp — both are data about where and when the value was sampled and
are preserved verbatim. The same path may appear more than once, each
pathvalue with its own $source.
