Authz is via the Policy objects and the syntax can be fairly arbitrary, specified by the Scheme, so there probably shouldn't be a need to add anything.

I'm not sure what you want to achieve, can you be more specific? The schema itself doesn't really have types anyway beyond string and integer. The basic limitation is that you can't have tables in objects, if you have more than one multivalued attribute in an object you can't connect them together because the order they come in is undefined, so if you want a table each row has to be a separate object. Also of course a single object can only have a single set of associations.
