I updated the default task.eddmod edd doc to add new elements to my catalog. How do I have the new element appear on FM application?

It looks like you've got two posts with the same question (in the structured forum) .. I'm just replying to this one.

When you update an EDD you must always import that EDD into the associated template. The structured application only references the template, so changing the EDD will have no effect until you import that into the template.

I have no idea how the Structure Application Designer works, so can't speak to that, but I'm sure the fundamental relationship of EDD to template still applies. If your EDD changes affect the model itself (adding/removing elements or attributes), you'll need to modify the associated DTD as well. Keep in mind that you can't just change the DITA DTDs and expect the result to be DITA compliant. There are rules about how to make these changes by "specializing" the model. If you change the model it may work for you in FM, but it may not work when you try to process or edit with other DITA-compliant tools.

One other thing to keep in mind is that if your change is something that you'd expect to be available in other topic types (other than "task"), you'll need to make the same edits to the other topic structure applications.

Maybe you'd have more luck in the Structured FM forum - this one deals only with unstructured...
