Existing Wording: Condition.dateAsserted = Estimated or actual date the condition/problem/diagnosis was first detected/suspected

Additional URL: http://hl7.org/fhir/2015May/condition-definitions.html#Condition.onset_x

Condition.onset = Estimated or actual date or date-time the condition began, in the opinion of the clinician

Proposed Wording: Condition.dateAsserted = date the condition/problem/diagnosis was first documented

Comment:

The definition of Condition.dateAsserted overlaps with Condition.onset, which raises questions about whether the dateAsserted is the when.recorded or when.init. The http://hl7-fhir.github.io/w5.html implies that condition.dateAsserted is aligned with when.recorded, yet the definition reads as if it is when.init. Update definition to reflect that the dateAsserted is aligned with when the condition was first recorded. Also, the Condition.asserter (who.author) should be consistent with the Condition.dateAsserted (when.recorded)
