Expected behaviour of ModRDN?

[Daniel Carroll <dan@mesa7.mesa.colorado.edu>]

I have some questions about the ModifyRDN operation in LDAP:

If I have an object, say: cn=blob, o=my org, c=us
And I execute the following modifyRDN operation on it:
   ldapmodrdn "cn=blob, o=my org, c=us" "cn=newblob, o=my org, c=us"
This moves the entry to: cn=newblob, o=my org, c=us,cn=blob, o=my org, c=us

(Yes, I am aware that I would normally specify the new RDN as "cn=newblob",
but I discovered the above behaviour before I figured that out....)

So:
  Is this the expected behaviour?
  If not, should this be an error?
  Is it legal to "move" an object deeper into the LDAP tree, using
    the ModifyRDN command?

Thanks.
