<div class="moz-cite-prefix">My present though is that this is
trying to convey at what zoom levels these features should appear.
<br>
These 'importance' tags are starting to appear for all different
kinds of things - aerodromes being one. <br>
<br>
So why not introduce a property tag (like width, height, capacity,
pressure) such as 'prominence' that can be use for any feature?<br>
<br>
And, yes, 'prominence' is subjective. If the scale has few values
then that will reduce edge cases and there will be few arguments
over which side a feature resides. <br>
<br>
(Yes I can hear the 'tagging for the render' cry from here
already. However this looks to be usefull information that mappers
want to tag. <br>
So give them a way of doing it and let the mappers and renders
chose to use it or not.) <br>

For better understanding: What the proposal tries to specify
is an<br>
importance rating for rivers based on their name, i.e. the
Garonne<br>
would by definition have the same rating everywhere it is
named<br>
Garonne. If the upper part of a river is named differently
than the<br>
lower part it would be a different river - hence potentially
a<br>
different importance rating (like Nile - Blue Nile/White
Nile or<br>
Rhein - Vorderrhein/Hinterrhein).<br>
<br>
This has very little to do with the size of a river as a
local property<br>
(like the width or the discharge) which a mapper would
normally use as<br>
a basis for tagging the size of a river.<br>
