One thing that comes up as a result of recent discussion on soapbuilders 
is the question of references to encoded data that spans headers.  In SOAP 
terms, I can have multiref objects on one header, and reference from 
another.  That doesn't specifically say unitdata isn't enough, but it 
suggests a lack of modularity in the headers that might need to be 
reflected at a core layer.  Not sure, but I think we should leave 
ourselves room to discuss this at the right time.  Thanks.

        Subject:        Modeling RPC with UnitData

I was asked by the WG to draft a resolution to the question of abstract 
modeling
of RPC; namely, is the UnitData primitive sufficient at the XMLP layer to 
model
RPC?   (The actual question was whether the UnitData primitive needed a
response-required parameter.)

One theory is this: It has now been agreed that RPC will be represented by 
a
module,  modeled on top of the XMLP layer, and it therefore does not need 
to be
represented by a state machine within the XMLP layer itself (thus the RPC 
nature
of a transaction is not visible to XMLP).

To bring this issue to resolution, I would like to ask if there is anyone 
not
comfortable with this approach. I am tasked with proposing a solution by 
noon
Monday; if there is no response to this, that is what I will propose.
