This message is missing message documentation, but it is assumed that $1 can have multiple elements, deciding if "label is missing" or "labels are missing". Furthermore, I could not find this message referenced anywhere in the code, so I fear it may be unused. Please resolve either way: * remove unused message, or; * add plural support and message documentation.
Looks like it's indeed not used. https://gerrit.wikimedia.org/r/#change,4959
