This specification attempts to maximize the useful lifetime of text directive links, for example, by +using the actual text content as the URL payload, and allowing a fallback element-id fragment. +However, pages on the web often update and change their content. As such, links like this may "rot" +in that the text content they point to no longer exists on the destination page.
+Text directive links can be useful despite this problem. In user sharing use cases, the link is +often transient, intended to be used only within a short time of sending. For longer duration use +cases, such as references and web page links, text directives are still valuable since they degrade +gracefully into an ordinary link. Additionally, the presence of a stale text directive can be useful +information to surface to a user, to help them understand the link creator’s original intent and +that the page content may have changed since the link was created.
+See § 4 Generating Text Fragment Directives for best practices on how to create robust text +directive links.
