You can do this write, but not automatically applying the change to each.

{
   "children" : [
     {
       "id" : "x1",
       "name" : {
         "connect" : "update",
         "lang" : "/lang/en",
         "value" : "XX4"
       }
     },
     {
       "id" : "x2",
       "name" : {
         "connect" : "update",
         "lang" : "/lang/en",
         "value" : "XX4"
       }
     }
   ],
   "name" : "XX1",
   "type" : "/people/person"
}

You will need to do a read query first to get the IDs of the children.
