Subject: Re: [ebxml-bp] [ebBP] Tell 6/14/2004: Business Contract Requirements for State Alignment
Monica, Not wanting to preempt discussion on Friday - but just wanting to throw out some technical ideas. What if we linked the signals to the begins/endsWhen conditionals on a BT? Just like with my proposal around linkage to context statements using a nameRefID - we could easily point to a named signal (it has that attribute already) and it would be either then boolean true or false. eg: beginsWhen="#mysignal-Is-On" This still leaves how the signal itself gets set of course! Seems like Dales post earlier may fit / hint into that category...since the only attribute in the signal right now is the URI - how does one actually turn a signal on?! If we can crack that "glue" then I believe we can provide what we need here. Am I also right in thinking that essentially used in this way the signals actually constitute the equivalent of an immediate "break" command so familiar in procedural languages to escape into/out of the current logical block. In our case that is of course a BT. DW ----- Original Message ----- From: "Monica J. Martin" <Monica.Martin@Sun.COM> To: "Anders W.
