We did consider allowing a bulk response to return data describing the 
affected objects, but decided against it. Returning data for each 
affected object would adversely affect performance and scalability. In 
some cases, such considerations might prevent a provider from supporting 
the bulk capability. (Several committee members expressed hesitation to 
support the search capability for these reasons.) The strongest 
argument, however, is that this behavior is not strictly necessary.

A bulkModify is a shorthand for search+modify. A bulkDelete is a 
shorthand for search+delete. Each operation represents an optimization 
that is possible when the requestor does not care about the list of 
objects affected.

When a requestor needs the list of affected objects (e.g., for 
client-side logging and monitoring), the requestor should issue a search 
operation and then modify or delete each item in the search result. This 
ensures that the list correctly corresponds to the set of objects 
modified or deleted. The set of objects modified or deleted will also be 
correct as of the point in time that the provider performed the search 
operation.

There is no need (in the strict sense) for a custom operation. However, 
the desirability of such a variant may justify defining it as part of a 
new capability.
