Static Enum definitions on the Swagger Specs

Hi, I need the way how the static core / client specific enum values supported on the dynamic configurations can be exposed my api  specs for dynamic configurations. In other words some enums will be defined on core while in some cases, the enums will be defined as part of client implementations. For example I have values for enum SRB, CRO, ALB, but client maybe want to add.  his own. How that can be achieved and exposed through API spec? And do you ned something more of the context?
