Hi Georg,
Just to be clear, are you trying to specialise the
openEHR-EHR-CLUSTER.laboratory_test_analyte.v1 archetype for specific
analytes, e.g. serum sodium, TSH etc?

Hello,
How do I constrain the Analyte result of a laboratory_test_analyte.v1 ?
The Analyte result are defined as an ELEMENT that is only constrained
by a node predicate (i.e. ELEMENT[at0001]). Therefore the results
cannot be bound with a specialized type and an alias within the FROM
part, as in the FROM part only archetypeID-predicates are allowed and
no node predicates. As the result is defined with the abstract ELEMENT
type, which has an abstract DATA_VALUE as its content, no paths can be
defined that constrain specific aspects of subclasses of DATA_VALUE
that are actually stored in the ELEMENT[at0001] field of the
test_analyte.
How can this problem be resolved ?
Greetings
Georg
