</div><div class="gmail_extra"><br></div><div class="gmail_extra" style>actually the layer tag doesn't state whether something is above, below or on ground. It is only a simple way to say: this object is above (when layer is higher) than this object (layer is lower). Still even for this there are exceptions: on shared nodes they are on the same level (e.g. beginning of bridge).</div>
