A DomainType can be composed of many DomainAttributes, each of which has a particular data type. Foreign keys are supported by declaring that a given DomainAttributes extends another through an ExtendsEdge. A DomainType can extend another DomainType through an ExtendsEdge to describe a simple form of inheritance. Multiple inheritance is supported, but circular inheritance is not allowed.[DomainType.html]
