Hi all, A question regarding the two term compositors mentioned in the subject: Should one expect that ExactlyOne is the non-greedy version of OneOrMore? That is, should an implementation attempt to satisfy as many terms of a OneOrMore compositor, whereas for an ExactlyOne compositor it would just quit as soon as there is found a term which is successfully evaluated / executed? In both cases, should it be a requirement for all terms to be valid against the agreement constraints, even if there are terms who satisfy them (the constraints) and were successfully evaluated / executed? Or are the above completely implementation-specific? Best regards, Costas
