Subject: Netid for DLUR owning CP respond searches in cross network environment

When a DLUR is located in a different network from its DLUS,
an owning CP respond search is sent from the dlus to the 
dlur for the purpose of properly routing the bind.  My question
is will the target LU name in this search be fully qualified with
the DLUR's NETID or will is use the DLUS's netid in the find
CV'82'? I couldn't find anything in the archetecture
relating to any special NETID considerations for replying to
the OCR search, so it seems that the DLUR's netid would
be the natural choice for this search.   In fact,
The DLUR architecture seems to imply that the SLU should be 
addressed by the DLUR's NETID even in flows beteen the
dlus and the plu host. (See notes for Figure 11.2 in the DLUR Arch.
Reference).

VTAM, on the other hand, seems to be sending this search with the
LU name qualified with the DLUS's netid.

If VTAM is hinting at the correct direction here, it seems
that the DLUR must remember the DLUS's netid from the CPSVRMGR
binds and pass this netid over to DS, so it can respond correctly
to locates.  Is this the correct approach?  If a backup dlus
is found with a different netid, the DLUR must re-register this
info to DS with the new netid, correct?

Looks like the architecture may need a little clarification
in this area.
