I don't have a really good answer for that one other than to say that the techniques are not normative, but it looks like text and not title may very well be required. I think we should bring this up as a discussion in a group meeting and come to a clear decision. As soon as the edit draft is approved and out of the way, I will suggest this as a topic.
