AMQP Management Operations

In reference to the AMQP Management Spec. v1.0 (wd02):
I see that for retrieving information about manageable objects in
a container there are a few options:
Use the  READ  operation to query a specific object by
name,
Use the  READALL  operation to query every object in the
container,
Use the  DISCOVER-NAMES  operation to get the names of all
objects and then  READ  to query individual objects.
I can envision situations where a given container may contain
very large numbers of objects (possibly millions).  In this case,
READALL and DISCOVER-NAMES will be impractical to use (i.e. they
will return with  413 - Request entity Too Large ).  Using the
optional  limit  argument doesn't appear to help.  The thing I'm
looking for may be beyond the limit and I'll never see it.
It would be good to have a way to query all objects of a
particular type.  Can READALL and DISCOVER-NAMES be altered such
that specific type names can be used, rather than only allowing
org.amqp.management ?
Thanks,
