Hi all, I understand that a topic ID must be unique within the scope of the root ditamap used for publishing the content. FrameMaker, which I used previously, creates IDs of the type id172OC0C03J7 So there is an arbitrary combination of 11 digits and letters. In oXygen I have set the "DITA > ID Option" as follows: ${localName}_${id} Which creates IDs of the following type: task_rf2_vcg_ywb So there is an arbitrary combination of only 9 characters, mostly letters. But perhaps sufficient for ensuring uniqueness... However, when I use the "DITA > Insert > Insert New DITA Resource" command, oXygen does not honor the "ID Option" setting, but creates IDs which are identical to the file name. This is not what I want and surely not suitable for ensuring uniqueness. How can I get oXygen to honor the "ID Option" setting or make it otherwise generate IDs with arbitrary characters which are likely to be unique?
