>>Variable definition --------------------- Section 2.4.2 is not clear about what kind of data a "variable" as defined here can contain. Should it be limited to info that are relevant to interaction? For example, in a credit approval choreography, while it's necessary to communicate the "approve"/"reject" decision, I don't see any reason a choreography should expose data used to make such decision. In addtion, variable definition is another example that different grouping criteria are used. I am very lost in trying to understand the differences of each kind of variables here I also note that the definitions are the same for "information exchange variable" and "information variable".
august f2f removed explicit state variable, which should clarify. Reclassify to editorial
22 sept 2004 included major editorial clarifications for variables.
