Description
There is a need to be able to identify and return child library expressions with the Library/$evaluate (i.e. not just the expressions defined in the library, but expressions defined in referenced libraries as well).
Propose that the list of expressions be allowed to include qualified identifiers. If the expression identifier is qualified, it refers to the name of an expression in a library, whereas an unqualified identifier still refers to an expression in the library being evaluated.
The tracker to support this is here: https://jira.hl7.org/browse/FHIR-46559

Research direction
Start at the Library/$evaluate operation and review the FHIR-46559 tracker for the intended qualified-identifier behavior. Trace how the current expression list is resolved for local and referenced libraries, then verify that unqualified names still resolve locally while qualified names return expressions from referenced libraries.
