Sorry, no good references off hand. I’ve had to help write & generate public docs in DocBook in the past. But no expert on either editors, nlp, or embeddings besides hacking around some tools for my own note taking. My assumption is youll want to use your existing markup structure, if you have it. Or naively split on paragraphs with a tool like spacy. Or get real fancy and use dynamic ranges; something like an accumulation window that aggregates adjacent sentences based on individual similarity, break on total size or dissimilarity, and then treat that aggregate as the range to “chunk.”

Thanks for the elaborate and helpful response. I'm also hacking on this as a personal note taking project and already started playing around with your ideas. Thanks!
