| Maps one DataAlterationRequest into another. This allows "filtering" of
an incoming train of DARs (probably resulting from a user request) into
a different form prior to being applied to the data model. This reshaping
might, for example, apply a remapping in order to unapply an
Entity -> ID mapping, or apply a security policy by throwing an exception
on a forbidden operation.
