Two operations require that you perform the operation for all items using one call to the message; they do not allow you to perform the operation incrementally on subsets of items, using multiple calls to the message. If you call these operations sequentially for subsets of the information, each successive call erases the established data from the previous call.
The operations that require you to perform the operation for all items using only one call are:
binder_setDefinitions: Associates entry types with workflow processes (see setDefinitions).
binder_setFunctionMembership: Sets access control for a workspace or folder (see setFunctionMembership).
