The > "/1" is optional if the version number isn't actually changing. Right, but if I do add the /1, consumers that haven't upgraded will break even though nothing substantive has changed. If there were something substantively different between 5451 and bis, so that consumers had to change to consume something other than the version number, I would probably be OK with the slash. But in this case, the slash doesn't solve any problem I can see, and is likely to cause some interop issues.
