It is not clear if OData enables a service to return a collection of heterogenous entity/complex types as a response to a function call.

I want to return a collection of types in response to a function call but each of the items in the collection could belong to different entity types.

Example:

/OData.svc/GetCreatedEntities?before=xxxx-xx-xx&after=xxxx-xx-xx

here GetCreatedEntities is a function call on my product that return a collection of entities that are Created in a given time period. Return Type is a Collection Type that could contain a Customer type, Order type etc.

Is it supported in OData?
