As Ian suggested I copy this issue from CKM to the technical list.
I have seen that in some archetypes (e.g. Apgar or BloodPressure) that
use DV_Duration restrictions (such as the width of the interval event
in the blood pressure archetype or the famous offset in the apgar
archetype) define them like this:
offset existence matches {1..1} matches {
DV_DURATION[at0040] occurrences matches
{0..1} matches { --
value existence matches {1..1} matches {|PT10M|}
}
}
As you can see, even if it is a single default value (10 minutes),
they are defined as ranges. As durations allow the definition of
default values (and they parse correctly) I think they should be
changed to this:
offset existence matches {1..1} matches {
DV_DURATION[at0040] occurrences matches
{0..1} matches { --
value existence matches {1..1} matches {PT10M}
}
}
As checking a concrete value is always easier than a range I would
suggest to change them to that.
