Greetings,
Am I suffering from acute caffeine deficiency syndrome (just made it
up) or is there a problem with the occurrences of event and
interval_events in the blood pressure archetype?
In the published blood pressure archetype in the CKM, HISTORY[at0001]
has events with cardinality {1..*; unordered}
However "EVENT[at0006] occurrences matches {0..*}" and
"INTERVAL_EVENT[at1042] occurrences matches {0..1}" under the history
allow zero instances of both of these elements.
So the cardinality sets 1 as the minimum member count for the
container attribute, but occurrences attributes of objects introduce
0, which is beyond allowed boundaries. In plain English: cardinality
says there has to be at least one, but objects say, there can be zero
or more. When both objects have zero instances, the cardinality
constraint is violated.Comments?
