#### Cross Version Analysis

This is an R4 IG. None of the features it uses are changed in R4B, so it can be used as is with R4B systems. Packages for both R4 (ihe.iti.vhl.r4) and R4B (ihe.iti.vhl.r4b) are available.

Package hl7.fhir.uv.extensions.r4#5.3.0 This IG defines the global extensions - the ones defined for everyone. These extensions are always in scope wherever FHIR is being used (built Sat, May 16, 2026 18:32+1000+10:00)

Package hl7.fhir.uv.tools.r4#1.1.2 This IG defines the extensions that the tools use internally. Some of these extensions are content that are being evaluated for elevation into the main spec, and others are tooling concerns (built Tue, Mar 24, 2026 11:13+1100+11:00)

#### Globals Table

There are no Global profiles defined

#### IP Statements
