      Will change the text of the rule to say "...the start will be less than or equal to the end".

      The rule isn't appearing in R5.

      The links to Period (and other datatypes) from the diagrams are not working.

    Description

      May we get clarification on the Period + Rule: If present, start SHALL have a lower value than end?  The invariant text does not match the invariant expression.  

       

      Invariants
      Defined on this element
      per-1 Rule If present, start SHALL have a lower value than end start.hasValue().not() or end.hasValue().not() or (start <= end)
