hello everyone,
I'm actually an ATL virgin, but I've found an interesting problem:
I've got a transformation with two input models which shall be merged into one new model based on some rules. It can happen, that an element x1 of input1 and an element x2 of input2 are marged to a new element xNew in the output. But based on the informations in x1 and x2 (if they eliminate each other) no element shall be created in the output. I first thought about a matched rule for x1 and x2 with no target-section. The do-section could be used to find out If they eliminate each other, if they don't, a called rule could be used to produce the element in the output.
Problem: matched rules without target-sections are forbidden Sad
any ideas, how to solve this problem?
Mats

I may suggest you match on input1 element and catch the corresponding
input2 element in "using" section with allInstances() + select
