However, what I want to do is transform ElementA to DefinitionB but if
there is more than one ElementA with the same name then all these
ElementA's need to map to one DefinitionB. I understand how this is done
in the example but in my metamodel the DefinitionB class is not associated
with other Classes and I'm unsure how to write this using just a match
rule.
I'd be grateful if someone could give me some tips on how to use ATL for
this kind of transformation. Thanks.
