Embedding and Reference Domain Relationship (Domain-Specific Language Designer)
You use domain relationships to establish relationships among domain classes in a domain-specific language definition. You can create an embedding relationship or a reference relationship in the Domain-Specific Language Designer by using the embedding or reference relationship item in the Toolbox. An embedding relationship appears as a solid line in the diagram, and a reference relationship appears as a dashed line. For more information, see Overview of Domain Relationships, How to: Add an Embedding Relationship to a Domain-Specific Language Definition, How to: Add a Reference Relationship to a Domain-Specific Language Definition, and How to: Add a Domain Relationship (DSL Explorer).
