Created by Bryn on 8/22/2016. Profiles within CQL allow the same underlying type to be accessed using different labels. When a profile is referenced, the ELM retrieve that is output will use the baseType of the profile as the dataType, and the name of the profile as the identifier. This allows the implementation to detect when the same data type has been accessed in a different way by the author. This mechanism is used in QDM to enable the negation pattern. For example, the Encounter, Performed data type is the same whether it is accessed positively or negatively, but the difference needs to be communicated reliably through the data access layer, so profiles are used, one positive and one negative. The underlying type Encounter, Performed, is not retrievable, only the positive and negative profiles. The identifiers are set to Encounter, Performed, and Encounter, Not Performed, and the resulting retrieve will reflect the EncounterPerformed type, together with the name of the profile, PositiveEncounterPerformed or NegativeEncounterPerformed, depending on which profile was used in the retrieve. NOTE: This behavior was subsequently changed due to the inconsistency it introduces between retrieves and general-purpose expressions. QDM still defines a base type with profiles for positive and negative aspects, but the retrieve will now return the profile type, not the base type. See github issue #131 for a detailed discussion of this change.
