nah, that’s not true at all. have a look at ‘rich-text’[1] which allows for transforms on metadata in a separate stream from the main content. it’s the same basic algo used for OT on plain text.

(i was the cto at a startup which used this to create a multi-user text editor with rich text support in 2015ish)

What's not true at all? That more powerful rich text editors need to rely on a tree structure?

[tkone]

yes. that is not true. you can build a rich text editor with simple ot. no tree necessary.
