Currently, when you specify not titles parameter for queries that require it, such as http://en.wikipedia.org/w/api.php?action=query&prop=info you get an empty result set: <?xml version="1.0" encoding="utf-8"?> <api /> Wouldn't it be more beneficial to return error in such cases, or at least to provide a notice that there is noting to query from? -- Max Semenik ([[User:MaxSem]])
