Richard, in enumerating the Things, I think there needs to be the addition
of Assessment (which I don't believe exists in schema) since a stand alone
assessment is also an established path -- "*Course* or Assessment". For
example the BCSP Certified Safety Professional certification example on the
wiki
<https://www.w3.org/community/eocred-schema/wiki/Catagorize_credential_by_type#2._Based_on_BCSP_Certified_Safety_Professional>
is an award based solely on a stand-alone assessment.
