I'm using Author to create DITA documents that have nested topics. An annoyance is that topics require the id= attribute, so having inserted a nested topic, I then have to set the ID even though I don't really care what the ID is. My questions: 1. Is there already a sample Oxygen extension that assigns IDs that I can use or adapt for this? 2. If the answer to (1) is no, where should I look for guidance on how to implement such an extension.
