// On iOS at least we want to be able to have several documents open in the same app process.
// It is somewhat complicated to make sure we access the same LibreOfficeKit object for the document
// in both the iOS-specific Objective-C++ code and in the mostly generic Online C++ code.
// We pass around a numeric ever-increasing document identifier that gets biumped for each document
// the system asks the app to open.
// For iOS, it is the static std::atomic<unsigned> appDocIdCounter in CODocument.mm.
// In practice it will probably be equivalent to the DocumentBroker::DocBrokerId or the number that
// the core SfxViewShell::GetDocId() returns, but there might be situations where multi-threading
// and opening of several documents in sequence very quickly might cause discrepancies, so it is
// better to usea different counter to be sure. Patches to use just one counter welcome.
