xADL 3 Domain Schema This schema defines the concept of a domain, usually applied to interfaces. In some architectural styles, (Myx, C2) interfaces have different domains that establish dependency relationships and topological layout. Changelog: - 3.0.0 * Initial version This enumeration defines allowable domains for interfaces in styles that support the notion of domains. They are: - top: Top domain. - bottom: Bottom domain. This type defines an element that can be added to another element to indicate its domain. This type is an extension that can be added to elements to give them a domain.
