  "description": "Defines the additional constraints and extensions on the UK Core Observation Vital Signs profile, for recording body height for adults and body length for infants and children . Body height / length is expected to be recorded in meters (m) or centimetres (cm) as per https://www.datadictionary.nhs.uk/nhs_business_definitions/height.html?hl=height.",
  "purpose": "To provide implementers with additional support when implementing length / height measuring and to provide a consistent structure to how the data is presented.",
