Issue

A clinical statement may have context conducted from its entry association. However, the Author participation is currently 1..*. In addition, the time attribute is 0..1 but required. These constraints are to restrictive.

Recomendation

• Change cardinality of Author Particpation from 1..* to 0..*
• Change conformance of Author.time from Required to Optional

Rationale

The 1..* cardinality on author requires systems to provide an author even when the author of the clinical statement is the same as the conducted author. The Required conformance on the time attribute requires systems to support this attribute even if they have no need to required the time of authoring.
