JSON encoding of payload to RESTCONF server for multiple resources creation

Question

Is it possible to send a single request of creating multiple resources at the top-level to a RESTCONF server?

For example, consider the following YANG module:

 module example-foomod {

 namespace "http://example.com/foomod";

 prefix "foomod";

 container top {
   container under1{
     leaf foo {
       type uint8;
     }
   }
   container under2{
     leaf bar {
       type uint8;
     }
   }
 }

}

Can I send the following request to create two resources one time? Or Must I create one resource at a time?

POST /restconf/data/example-foomod:top

payload is:

{
 "example-foomod:under1": {
   "foo": 54
 },
 "example-foomod:under2": {
   "bar": 45
 }
}

I didn't find answer in RFC7951. It seems like all examples in that RFC are single resource, like in section4.
