 The SDPi Reporting profile builds on the basic <<acronym_pnt>> capabilities of the <<acronym_sdpi_p>> profile, but adds the requirements to fully support *_medical data reporting_*.
 To that end, this specification fully supports the safety and security requirements in the <<ref_ieee_11073_10701_2022>> metric reporting <<acronym_pkp>> standard.
