Description
This change implements a new function, normalize:
collection<Coding> -> normalize() : collection<Coding>
This function takes a collection of Coding elements as input. The result is a collection of the same number of Codings, but each subset of equivalent Codings within the collection will be assigned the same "normalized" value. The new values for this subset of Codings will be equal according to the semantics of the equality operator.
Equivalence semantics will be the same as for the equivalence operator.
This function can be used to normalize Coding values prior to grouping, to merge equivalent Coding-based groups.
Example:
Condition.code.coding.normalize()

Research direction
Start by reading the proposed FHIRPath normalize() signature, its Coding input and output semantics, and the linked equivalence-operator issue (#300). Done means equivalent Codings receive equal normalized values while preserving collection size, supporting grouping use cases such as Condition.code.coding.normalize().
