I think the problem is that we've painted the metadata bucket as the 
place to put information that you don't need echoed back in messages 
addressed to the EPR (its just info about the EPR). The security stuff 
that Rich outlined is required to be sent back so its closer to 
reference parameter semantics except that reference parameters are 
serialized as direct SOAP headers whereas the requirement here is to 
create a wsse:Security header or add to an existing one. We could 
define a sub-bucket for this information and describe the additional 
processing semantics for the contents of this sub-bucket or we could 
add a new security element to the epr.
