The idea is to send the entire collection elements every time a user wants to update a single usage otherwise the missing elements will be automatically removed from the collection. Example: having <usages><usage>VM</usage><usages> 1. in order to add 'display' usage to the collection i must send 'vm' as well. 2. to remove an element from the collection, i must send the entire collection without the desired element (note: in this case it is only one extra element for every update but in other cases it could be much more) The solution should be: <usages><vm>true</vm><display>false</display></usages> That way we can send a single usage having different boolean text without including the entire collection elements.
