Hello,
I have a question the is a bit related to the discussion about the
constraining of the ELEMENT type in the laboratory_analytes.
The current specification defines the field "ehr_status" of the class
EHR with the type OBJECT_REF. In the AQL specification there is an
example (chapter 3.7.2.3. NOT) that accesses this field with the
assumption that the field is of type EHR_STATUS.
I have written a type checker for AQL queries, so I am now stumbling
across queries that access fields of potential subclasses or derived
archetypes.
Does/should the specification generally allow such a thing ?
Greetings
Georg
