Nexus EMR profile for MedicationDispense resources, primarily for recording dispense events. Aligns with CII N1/N2 requirements and Nexus EMR standards.

Salient fields

The profile's synthesized-accessor contract: fields TypedFhir surfaces as first-class typed properties, each computed from the instance by a restricted FHIRPath expression. See Salient Fields for what they are, how they shape LLM contexts, and how to declare them.
