Well, it would be difficult for me to say I disagree with this proposal since I
use as much as possible UML 2.0 in this specification. My concern is for
end-users in a near future. At Barcelona, a guy asked me why we use the term
protocol diagram to represent interaction protocols in AUML since he knows
sequence diagrams and not protocol diagrams. If we think FIPA AUML is indebted
to AUML, we have several names and the new one will need time to be accepted
since UML 2.0 is so new that a lot of people don't know it exists. Moreover, it
is the problem of consistency for people reading  _old_ papers on AUML and new
