Sightings of Observables with Descriptions

["Mates, Jeffrey CIV DC3/TSD" <Jeffrey.Mates@dc3.mil>]

I ran into a bit of weirdness when modelling some data I received in STIX 2.1. 
In this case it was with sensor data that had descriptions descriptions, and 
from what I can see the only way to get a description of these is to:

1. Create the SCOs
2. Make observations of the SCOs
3. Make a sighting of the observations of the SCOs with a description

I suspect it is now too late to do this, but it could be useful if Observed 
Data objects include a description property or if Sighting could be a sighting 
on an SCO directly in order to shorten this chain.  If others have run into 
this issue I'm curious how you worked through it.
