I'm not sure that's necessary because D127762 already added tests to ensure the attributes propagate on pointer types, which then sets the ExtProtoInfo for those values. This patch merely checks the SME attribute fields from ExtProtoInfo. i.e. there is already nothing depending on a declaration being available.
