GR: should PA be able to query the RA?  Answer: in general this is required for NSA recovery.  However, we have a 
difference of opinion about query variants. TK: 2 variants of query, i.e  query response should be different on RA 
compared to PA (different role and different response information).   JS: believes that only one variant of query is 
required, i.e RA and PA can use the same query response type (same information).  Response to a query should be optional
.
Summary: we need to decide if there is 1 or 2 query types and if we want to support PA -> RA query
