Hi Ugo,

Thank you very much and another alternative approach that we would like to 
see in BPMN (Binary) Collaboration process diagrams is as a self-contained 
process specification in single pool but defined over say three lanes: two 
lanes for place activities performed by collaborating roles and a middle 
lane for a shared space to place intermediate events with global interest 
(i.e. for two parties). 

This would be somewhat similar approach to the standard pattern of  a 
transaction as in http://infolab.uvt.nl/grnsd/lap2003/dietz.pdf defined by 
Jan L.G. Dietz (http://is.twi.tudelft.nl/ontwerpen/people/dietz.html) 

Any comments?
