       Multiple occurrences of CodeSystem.concept.property may occur for a CodeSystem.property where CodeSystem.concept.property.code is the same and CodeSystem.concept.property.value differs.  For example: multiple designations for a single concept.

    Description

      The spec doesn't make clear that code properties can repeat (i.e. multiple occurrences of the same property for the same code).  It needs to.  As well, we should add a flag when we define CodeSystem properties that indicates whether repetitions are allowed or not (so we don't have a situation where properties that aren't allowed to repeat are specified more than once, and so that systems are clear when multiples are allowed (e.g. concept parent).
