This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Section 8.2.1.3 Optional tags currently contains the folllowing: An rt element's end tag may be omitted if the rt element is immediately followed by an rt or rp element, or if there is no more content in the parent element. An rp element's end tag may be omitted if the rp element is immediately followed by an rt or rp element, or if there is no more content in the parent element. I propose to remove this from the spec. Reason: The general arguments against optional end tag are valid (more exceptions, thus harder learn, additional work when migrating to XHTML) However in case of the rt und rp elements they have never been in a HTML specification, thus there are no backward compatibility issues.
EDITOR'S RESPONSE: This is an Editor's Response to your comment. If you are satisfied with this response, please change the state of this bug to CLOSED. If you have additional information and would like the editor to reconsider, please reopen this bug. If you would like to escalate the issue to the full HTML Working Group, please add the TrackerRequest keyword to this bug, and suggest title and text for the tracker issue; or you may create a tracker issue yourself, if you are able to do so. For more details, see this document: http://dev.w3.org/html5/decision-policy/decision-policy.html Status: Rejected Change Description: no spec change Rationale: I disagree that omittable end tags are bad. They can make writing markup far less verbose, and are completely unambiguous. Nobody is forcing anyone to omit them.
I don't fully agree but I accept your response.
