Currently it is possible to restrict the type and size of the uploaded assets (https://documentation.magnolia-cms.com/display/DOCS60/DAM+upload+field).
But when allowing the "Upload ZIP archive", the size and type of the media inside the ZIP archive cannot be restricted.

As ZIP upload is a good feature also for editors which are not allowed to create assets of any type/size there should be also a way to restrict the type/size of the files inside the ZIP archive.

Any valiation/limitations that apply to a single Asset upload must also apply to a zip upload. All valid assets should be imported. Any non-valid assets should not be imporeted and a warning message should be displayed and stored in messages.
