Статус: draft. Extension maintained by: Health Level Seven, Inc. - FHIR Core WG

A FHIRPath statement that defines whether an element is in the slice.

Comment:

This extension can only appear on element definitions that are part of a set of slices, and not on the slicing definition itself. If the selector appears in the presence of nominated slices discriminators, then the slicing defined by the discriminator(s) and the selector on each slice must agree. In the absence of any nominated discriminators, then an element is allowed to be in multiple slices.

Context of Use: Use on Element ID ElementDefinition

usage info: insert a list of places where this extension is used
