WarningObservation.hasMemberElements differ in definition: 'A reference to another Observation profiled by Observation-results-laboratory-uv-ips. The target observation (for instance an individual test member of a panel) is considered as a sub-observation of the current one, which plays the role of a grouper.' vs 'This observation is a group observation (e.g. a battery, a panel of tests, a set of vital sign measurements) that includes the target as a member of the group.'
WarningObservation.hasMemberElements differ in comments: 'This element is used in the context of international patient summary when there is a need to group a collection of observations, because they belong to the same panel, or because they share a common interpretation comment, or a common media attachment (illustrative image or graph). In these cases, the current observation is the grouper, and its set of sub-observations are related observations using the type 'has-member'. For a discussion on the ways Observations can be assembled in groups together see [Observation Grouping].' vs 'When using this element, an observation will typically have either a value or a set of related resources, although both may be present in some cases. For a discussion on the ways Observations can assembled in groups together, see [Notes] below. Note that a system may calculate results from [QuestionnaireResponse] into a final score and represent the score as an Observation.'
