Thank you guys for your prompt responses.
I shouldn't be surprised that there are many ways for defining a
sequence using meta-GME. I also thought on embedding the ordering in an
add-on/interpreter, but I wanted it to be explicitly shown in the
meta-model. I thought of following Chris' visual suggestion because it
seems simpler/more intuitive for model developers to define (that is
instead of having the "order" attribute). Then again the OCL constraints
for enforcing a single head and tail, but many "bodies", might get
tricky (complex). Joe's OCL simplification for the explicit ordering
attribute also looks "attractive".
I suppose that I need to weight my choices..
Thanks for the annotations hint Larry - that will do for the moment!
Once again, thanks for your prompt responses!
