If you are converting your installation from InterFormNG into InterFormNG2, then you should notice, that the InterFormNG2 workflows are totally different than the InterFormNG workflow/rules.
The InterFormNG2 workflow works the same for both InterFormNG2 and InterFormNG templates, but customers that are converting an InterFormNG installation into InterFormNG2 should keep in mind, that the output formats (that are often set inside the InterFormNG template) are not used in InterFormNG2, so you need to setup a special workflow to handle InterFormNG templates, if you want the InterFormNG template to dynamically set the type of output and settings for the output.
The specifics to keep in mind, when it comes to implementing InterFormNG templates in InterFormNG2 are covered here.
If you want to merge an input XML file with an InterFormNG template (.itpl) and let the template decide all output settings, then you always first need to merge into the intermediate format with the workflow component: From ITPL to intermediate.
You can even combine the from ITPL to intermediate component with a generic workflow, that you can call to create any kind of output, that is selected in the InterFormNG template. This can e.g. be used, if the meta data key, mediaType is set in the InterFormNG template. The mediaType meta data key is not used in the InterFormNG2 workflow, but you can implement it yourself in a generic workflow like below.
