Update this informative remark to not only indicate that the page is informative, but also that implementers should carefully read and understand its content. So, something like: This page contains guidance to implementers and is not part of the normative-track; however, implementers are strongly encouraged to read and understand its content towards successful synchronization. Also, review and rephrase any normative verbs that exist on this page: 1. Use editorial discretion to not use lower-case shall/should/may. 2. Move this normative requirement to elsewhere in the spec (probably the syncerror definition page): A Client that initiates a context change and receives a syncerror related to a context change event it send, *_SHOULD _*resend this event at regular intervals until sync is reestablished or another, newer, event has been received
