Generated Narrative: CodeSystem resource-slicing-rules

This case-sensitive code system http://hl7.org/fhir/resource-slicing-rules defines the following codes:

Code	Display	Definition
closed	Closed	No additional content is allowed other than that described by the slices in this profile.
open	Open	Additional content is allowed anywhere in the list.
openAtEnd	Open at End	Additional content is allowed, but only at the end of the list. Note that using this requires that the slices be ordered, which makes it hard to share uses. This should only be done where absolutely required.
