Location with Address Variation 1 (LA1) -- HL7v2 composite data type.
Specifies a patient location with an optional address. Used for dispense-to

1. Point of Care (IS)
2. Room (IS)
3. Bed (IS)
4. Facility (HD) -- sub-components
5. Location Status (IS)
6. Patient Location Type (IS)
7. Building (IS)
8. Floor (IS)
9. Address (AD) -- sub-components (street, city, state, zip, country, type)
