- *Enhancement:* Identifier formatting and parsing moved to the `CosmosDbArgs` to enable overriding where required.
- *Enhancement:* Cosmos model constraint softened to allow for `IEntityKey` to support more flexible scenarios.
- *Fixed:* `PagingOperationFilter` correctly specifies a format of `int64` for the `number`-type paging parameters.
- *Fixed:* `CompositeKey` correctly supports `IReferenceData` types leveraging the underlying `IReferenceData.Code`.

…ed to the `CosmosDbArgs` to enable overriding where required.

- *Enhancement:* Cosmos model constraint softened to allow for `IEntityKey` to support more flexible identifier scenarios.
- *Enhancement:* All Cosmos methods updated to support `CompositeKey` versus `object` for identifier specification for greater flexibility.
- *Enhancement:* `CosmosDbModelContainer` and `CosmosDbValueModelContainer` enable model-only access; also, all model capabilities housed under new `Model` namespace.
- *Fixed:* `PagingOperationFilter` correctly specifies a format of `int64` for the `number`-type paging parameters.
- *Fixed:* `CompositeKey` correctly supports `IReferenceData` types leveraging the underlying `IReferenceData.Code`.
