+ * in the beginning.
  *
  * Throws if the sessionId/txnNumber combination is not properly formatted.
  *
  * requiresAuth specifies if the command we're initializing operationSessionInfo for requires
  * authorization or not.  This can be determined by invoking ->requiresAuth() on the parsed command.
+ * If it does not require authorization, return boost::none.
  *
  * Both isReplSetMemberOrMongos and supportsDocLocking need to be true if the command contains a
  * transaction number, otherwise this function will throw.

+ * On success, returns the parsed request information. Returning boost::none implies that the
+ * proper command or session requirements were not met.
