accessModifier - The bitwise flag specified to determine
if certain normal security checks are to be
bypassed for this delete request.
For example:
if the accessModifer is NOACCESSCHECK, then the
check for the object's NODELETE flag and the
call to the object's canDelete() method
will not be performed.
If the accessModifer is NONE, then all the
access checks are performed before this object
is marked delete.
