      We propose changing Observation.focus to MS. There may be corner cases where a PrimaryCancerCondition is not available, so making it required presents some risk of not receiving staging data.

    Description

      Currently, the Observation.focus attribute bound to PrimaryCancerCondition is optional and not must-support. This needs to be at least MS, and potentially a required attribute since staging has no meaning without its association to a primary cancer condition. Moreover, it is possible for one to have multiple primary cancers and without enforcing this, one doesn't know which cancer the stage is related to.
