Steps to reproduce:

1. Go to [maintenance.create|create], [maintenance.update|update]
2. 
3. Click on Hosts
4. 

5. Try to send request "params": { "hosts":[

   { "hostid":"12345", "host":"example.com" }

   ],...

Result:
"error":

{ "code": -32602, "message": "Invalid params.", "data": "Invalid parameter \"/1/hosts/1\": unexpected parameter \"host\"." }

Expected:
More accurate documentation stating that only the hostid property should be used and no other. The link to the Host object only confuses.
