We will submit a change request to exclude the abstract code from the valueset as we can't conceive of a use-case where, in this situation, the abstract code will be needed. We will also raise a change request to consider in R5 that will address the more general question of how to indicate in a binding whether abstract codes should be included (or not) in an expansion and more clearly rendering in value set expansions whether a code is defined as 'abstract' in the underlying code system.
