862	the concepts system needs to recognize required vs unrequired concepts	eugene	Paul Price	"if a concept if missing from an image being loaded, sometimes this is an error,
sometimes it is only information.  If my program does not need to use the
concept, it is not necessary to raise an error if the concept is missing.

a possible solution is to require the calling program to specify the concepts it
will require before the concepts are parse."	defect	closed	high		concepts	unspecified	normal	fixed
