description: To promote interoperability and adoption through common implementation, this profile sets minimum expectations for the AllergyIntolerance resource to record, search, and fetch allergies/adverse reactions associated with a patient pm2.  It identifies the mandatory core elements, extensions, vocabularies and value sets which **SHALL** be present in the AllergyIntolerance resource when using this profile. It provides the floor for standards development for specific uses cases.
