Package File

The following package file includes an NPM package file used by many of the FHIR tools. It contains all the value sets, profiles, extensions, pages, and URLs in the IG which are defined as part of this version of the Implementation Guides. This file should be the first choice whenever generating any implementation artifacts since it contains all of the rules about what makes the profiles valid.
