The first paragraph of 1.2 is not fair. The FHIR core has as much guidance as v2 core and CDA core. All of them require an IG to add to them. This paragraph is unnecessary and not helpful. The previous section has already made the v2 and cda linage clear. Remove this paragraph

Unlike HCS-based security labeling guidance provided by HL7 Version 2.9, the CDA Data Segmentation for Privacy (DS4P) Implementation Guide, and the CDA Data Provenance IG, the FHIR Security Label Module does not provide detailed implementation guidance for FHIR implementers, because the FHIR core is agnostic to the HCS syntax requirements (although this guidance will likely be updated to reflect this IG’s specifications to some extent.)
