How to store dictionaries with non-uniform key or value classes?

[pdebruic]

Hi -

the ZnHeader class (part of the Zinc http library) can/does hold strings as keys but a variety of objects as values (e.g. ZnMimeType, Integer, String). Which all can be emitted as strings in a ZnRequest or ZnResponse.

How would you define a #reStoreDefinition for that use case?

Thanks
