A control which results in modification of multiple objects must not be 
partially applied, but what about a control that modifies the behaviour 
of a query? A control requesting extra information from each entry in a 
search result, for example a control to reproduce the behaviour of the 
modifyRightsRequest in a DAP read operation, may be partially applied, 
without having any serious implications. To what extent should the 
allowance to partially apply a control be regulated by the specification 
controlling the infrastructure, i.e. [protocols], versus the control 
specification? For example, a control specification for a tree delete 
control should include a discussion of considerations relating to 
application of the control in a distributed environment or across 
different contexts, regardless of what [protocols] may say.
