Description
Section 1.1.5.1 states that The LIVD catalog profile is based on the Catalog profile based on the Composition resource. In fact this is not the case: Section 2.3.1.1[http://hl7.org/fhir/uv/livd/2019SEP/catalog-uv-livd.html#profile] which specifies the LIVD catalog profile build it directly upon the Composition resource.
Building the LIVD catalog profile on top of the existing Catalog profile seems as a good idea since LIVD is a kind of catalog. This brings a constraint on the content of Composition.section.entry, which is [1..*] and of the mandatory datatype Reference(CatalogEntry).
This is a major change to consider on LIVD IG
