Supporting files such as .blend etc? Unclear...

When submitting to the asset store can I include files such as .zip, .blend, etc? Or is this strictly not allowed?

 

I don't think we can use archives but I have no idea about .blend files. Reason I said this about archives is that for about a year I had been packing script dependencies into a .unitypackage file, which is basically an archive, and out of the blue this was a reason why my update was rejected. Maybe this is a new requirement for assets.

On that note I have yet to find a page listing what can and cannot be put into a unity asset package. I don't know if one exists yet but it could be pretty useful.
