Will add clarification on the approach that this IG is using to incorporate code systems and value sets from the Gravity Project terminology workstream.  Updates will be made to accommodate an observation resource that is not derived from the survey/assessment and the inclusion of SNOMED-CT to describe goals.  In addition, we will describe the use of the supplemental guide as an interim solution until the additional capability to use value set metadata is added to FHIRPath and can be used to select a value set specific to an instance of a resource (based, in general, on the value in .category)
