This is intended to deal with the confusion routinely created by haing two conflated concepts of being in a particular state and having achieved a particular milestone. In strict terms a milestone is a point of time event that results in a change from one state to another. The state before the milestone is achieved is often given the same name as the milestone, and sometimes the state may have the same description. For instance "Randomised" and "Visit 1" may be different milestones but the state remains at "on study" after each of them.
It is likely that more than one "state" pattern will be recorded for a subject and a type has been introduced to allow this simultaneous recording.</td></tr><tr><td>ResearchSubject.progress.type (type)</td><td><a href="CodeSystem-concept-map-relationship.html#wider" title="wider">maps to wider concept</a></td><td>Extension.extension:type (R5: state | milestone (new))</td><td>Element `ResearchSubject.progress.type` is part of an existing definition because parent element `ResearchSubject.progress` requires a cross-version extension.

value="Element `ResearchSubject.progress.milestone` is part of an existing definition because parent element `ResearchSubject.progress` requires a cross-version extension.
Element `ResearchSubject.progress.milestone` has a context of ResearchSubject based on following the parent source element upwards and mapping to `ResearchSubject`.
Element `ResearchSubject.progress.milestone` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element).
There can be multiple entries but it is also valid to just have the most recent. This should npt be rlied upon as the full path the subject has taken."/>
