Description

Goals:

• Support bookmark resolution to handle alias names. (Introduce `@DomainObject(aliased=...)` and `@DomainService(aliased=...)` annotation attributes)
• Support for `@Named` annotation on concrete types, abstract types and interfaces.
• Deprecate annotation `@LogicalTypeName`.
• Deprecate annotation attribute `@DomainObject(logicalTypeName=...)`.
• Deprecate annotation attribute `@Value(logicalTypeName=...)`.

Non Goals:

• No injection point resolution based on alias names. (Naturally so, because it is based on types not names anyway.)
• No modification to the Security Model (SecMan): Permissions are checked against primary logical member names, not involving aliases.

Implications:

• Must be supported by SpecificationLoader#specForBookmark and Restful DomainObjectResource and its friends.
• Must also support service lookup based on alias names (ServiceRegistry).
