Thank you Thomas,
The use of URI's is well known, but just not fitting with the billions of HL7 v3 implementations. As long as identification is correct each variant of ids is fine.
I partly agree to your point here:
codeSystem="2.16.840.1.113883.6.96
This is not how it normally appears in an DCM or HL7 v3 message and i suggest should not appear in an archetype.
Normally it reads like
\
But good to know that refering to this is now possible in archetypes
vriendelijke groeten, with kind regards,
