{{msg-mw|Revdelete-radio-set|notext=1}}
Fragment of a discussion from Support/LiquidThreads
It is a part of the RevisionDelete feature. The message is a caption for a column of radioboxes inside a box with Revdelete-legend ("Set visibility restrictions") as a title.
There are three radio buttons in each row, and the captions above each column read Revdelete-radio-same ("Do not change"), Revdelete-radio-set ("Hidden"), and Revdelete-radio-unset ("Visible").
