How to store Pathological examination result in CDM

@karthik @HuaXu @jon_duke @mgurley @Dymshyts and @Christian_Reich, we need to communicate how ETLs to the oncology extension should handle some of the more definitive sources of information about conditions - e.g. stage - in the MEASUREMENT table/domain. People doing these ETLs will use NLP and will need guidance re what concepts belong in note_NLP_concept_id in the NOTES_NLP table. Does the original rational for having Condition concepts in NOTES_NLP extend to these concepts? If so, should they go into both MEASUREMENT and NOTES_NLP? If so, are these concepts for conditions and measurement domains in NOTES_NLP used differently or completely redundant?
