        <div>Well first, tunnel=yes is obviously wrong. We need to
          replace this with cave=yes. Other than that, I have no
          problems with this. If a cave has two cave entrances, then
          information that they are connected by footpaths is valuable
          information. <br>

    Obviously?  Regarding paths and waterways, especially ones fitted up

                            how<br>
                            these may be mapped ("tunnels that are
                            available for humans but closed for typical<br>
                            tourists may be mapped as highway=path with

                            <br>
                          </div>
                          I think that it is an obvious idea, but wiki
                          claimed that "At the moment there just a <br>
                          tag to map the entrance to a cave." despite
                          fact that existing tags fit well.<br>
                          <br>
                        </div>
                        I am pretty sure that it is a good idea, but
                        maybe there is some superior scheme or<br>
                      </div>
                      I missed something.<br>
                      <br>

                    Example of cave tagged this way is available at <a

                    <br>
                  </div>
                  I wonder about adding something that would denote that

                  maybe natural=cave_tunnel?<br>
