The information about logical identifiers, literal identifiers, business identifiers, canonical urls and their associated versions is spread over various places and is hard to collate.
I suggest that the section 2.28.3.2 Resource Identity needs a new subsection (a sibling to 2.28.3.2.1 "Business" Identifiers) for canonical identifiers of FHIR resources (e.g. StructureDefinition.url). Their importance is lost by just mentioning them in the sentence: "In a few resources, there is a url element that serves a similar purpose, but is constrained to be a literal URL for implementation reasons."
The section should mention the new data type (canonical) and something of their use.
Maybe it could also refer to 2.3.0 Resource References
