FpML-BP Issue with messaging for "same party - multiple roles" cardinality on a trade/contract.

[Henri Pegeron <hpegeron@xxxxxxxx>]

All,
There has been some recent discussion about A2A message flows and situations
in which a single entity trades with itself.  

Following those discussions I've found
that from the perspective of a service provider, this will happen much
more often than it would usually seem.  A centralized provider is
often only exposed to one consolidated entity at any given firm which may
represent multiple internal ones.  Whenever any of those unique internal
entities need to communicate with each other through a central provider,
it will appear as if the entity is trading with itself.  This happens
quite often today.

The problem with this is that FpML enforces
via schema that 2 (or more) "unique" entities must communicate
with each other.  This makes it impossible to accommodate the above
scenario without a change to the cardinality of the party elements in those
messaging types. 

I've submitted an issue regarding a problem with notification messaging
in FpML here: http://www.fpml.org/issues/view.php?id=310


Regards,
Henri Pegeron
