  "description": "Local stand-in StructureDefinition — not an official HL7 resource, not served at the hl7.org URL below. Resolves a canonical URL that de.fhir.medication's DosageDgMP references (DosageStructuredRequiresGeneratedText). HL7 International does publish this extension, but only as an unstable pre-release (hl7.fhir.uv.xver-r5.r4, FMM 0, trial-use) that de.fhir.medication itself deliberately avoids depending on (see its 1.0.6 release notes). We pin our own stable copy instead; content is equivalent (verified against the official extension). Published only for validator resolution.",
