// Phase 17 sitemap served is copied, a relative path with a leading slash
// and spaces and unsafe bytes percent-encoded; a duplicate is kept once
// and not reported; an item that still is no allowed address, and a
// malformed one, is dropped with its reason while the others are kept;
// items of another type are neither kept nor reported.
