+ * IPC Transaction protocol for the WebAuthn DOM API. This IPC protocol allows
+ * the content process to call to the parent to access hardware for
+ * authentication registration and challenges. All transactions start in the
+ * child process, and the parent replies with a "Confirm*" message, or a
+ * "Cancel" message if there was an error (no hardware available, no registered
+ * keys, etc) or interruption (another transaction was started in another
+ * content process). Similarly, the content process can also request a cancel,
+ * either triggered explicitly by the user/script or due to UI events like
+ * selecting a different tab.
