     * In Pure, these fields are defined as string and not properly resolved, perhaps because of
     * the fact that in Pure, we allow mappings which contain class mapping IDs pointing at
     * another mapping's class mappings. In Pure/Engine, we let this pass compilation phase.
     * In Studio, we disallow this. This makes it hard for users to migrate to Studio.
     * We should think of a strategy to make things loadable in Studio, but disallow users
     * to make changes if they have this kind of error in their graph.
     *
     * See https://github.com/finos/legend-studio/issues/880
     *
     * NOTE: We might not be able to resolve `targetSetImplementation` for all `target` IDs hence
     * defined as optional for now. We might need to come back and re-visit this decision. Note that
     * one quirky thing is that the metamodel in Pure has these fields as string pointers, even
     * when these are not resolvable, the field is set to empty string. We should solidify our
     * understand about these fields.
