Several act relationships in the pattern have attributes : contextControlCode – [1..1] Required.

(These are currently : sourceOf2, sourceOf1, component, precondition (from ObservationRange), precondition (from choice box), referenceRange.)

The NHS in the UK do not currently plan to use context conduction of acts across act relationships, and so don’t need these attributes.

However, as 1..1 Required, it is not possible for UK models to be compliant without including them. They must even be sent as as values in xml instances.


  • Relax these attributes to be 0..1 Required.


This means the attributes must still be present in Clinical Statemtent compliant models, but need not be used, and can be missed out of instances. This will allow existing NHS messages to be compliant, but not allow models to ignore context conduction altogether.


Noted there are problems with Act to Act participations
