<p class=MsoNormal><font size=2 face=Tahoma><span lang=EN-GB style='font-size:

attributes change frequently, for example for bridges, changes in name, changes
in ‘ref’, changes in ‘ncn-ref’, ‘surface’
etc etc.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Tahoma><span lang=EN-GB style='font-size:
10.0pt;font-family:Tahoma'>It seems that one is allowed to have overlapping
ways (certainly JOSM allows this to happen) each with some of the tags; however
it is impossible to maintain in JOSM if one does do this, normally by mistake I
my case then MapLint complains about it.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Tahoma><span lang=EN-GB style='font-size:

<p class=MsoNormal><font size=2 face=Tahoma><span lang=EN-GB style='font-size:
10.0pt;font-family:Tahoma'>However…. if I snip up the ways every time there
is the slightest change in the associated tags then OSM_Render messes up the
rendering, repeating the names each time. See <st1:Street w:st="on"><st1:address

I now intend to add references for the local and regional cycle routes, and

<p class=MsoNormal><font size=2 face=Tahoma><span lang=EN-GB style='font-size:
10.0pt;font-family:Tahoma'>So… should I somehow be using multiple
overlapping ways (I hope not), or should I be snipping the ways up whenever a
tag changes and leave it to OSM_render to sort out the rendering side in due
course.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Tahoma><span lang=EN-GB style='font-size:

name (4A for example), a national name (N1 for example) and also possibly a
regional name (‘suffolk coastal route’, ‘R21’) then
should I put all of these under the same ncn-ref tag separated by a semi-colon
(‘4A;N1;Suffolk Coastal Route’) or should we be inventing a new tag
for local cycle routes (‘lcn_ref’ for example) and regional cycle
route (‘rcn_ref’ for example).<o:p></o:p></span></font></p>
