I've read somewhere that navigation software will split all
ways at a crossing in order to be able to calculate all
possible routes. So the merging is only needed for rendering
(in order not to show the name over and over again).</div>

Obviously.<br>
With my method, there is no merging necessary because there is no
splitting.<br>
If a part of a way has different tags, a sort of "patch" dummy way
is created that overlays that part of the way and that contains the
tags that are different. Difficult to explain in 2 lines.<br>
<tt>--------------------------------------------------- </tt><tt>real
highway with common tags<br>
------------- dummy way
(patch) with bridge=yes<br>
</tt>If the consumer wants that, it can split the real highway,
merge the tags and get the current situation. But it doesn't have
to. <br>
In a further step, with slight software changes, the patch could be
the element of a relation and relations would stop splitting the
ways everywhere.<br>
Also, a turning restriction and other things could be done with very
simple patches instead of complicated relations.<br>
All in all very powerful and easy to use, but, alas, it needs
software changes. Nothing complicated but in the essential parts.<br>

If you click on <span class="type"></span><span class="details">(<a

of [2] you see that it's only a split of Molenstraat and if you

not very clear at all how that street is split</a>, it looks like
Nominatim is only showing parts of the splits.<br>
It would obviously work better if there were no splits but patches.<br>

PS: Oops, I first thought that "molen" were moles and I wondered if
they were under the street and <a
href="http://www.openstreetmap.org/way/166577477">drinking a cup
of coffee</a> <span class="moz-smiley-s3"><span> ;-) </span></span>
They are in fact mills <a
href="http://www.openstreetmap.org/node/259975902#map=19/50.52639/5.52305">like
this water mill</a> that I just mapped and that's probably the
best known in Belgium.<br>
