I don't see any immediate problems with this. But doesn't creating these properties require to solve the same problem with the specific cases we are discussing now? > Or would this just overwhelm the text property mechanism? No, I don't think it should. Text properties scale reasonably well. And we already have the same with faces (since comments have a specific face), don't we?
