Ooh, a golden opportunity to point out (to Richard of all people :-) )
that the key / value pairs are just arbitrary UTF8 strings and can
mean whatever we want them to mean. So the letters n-e-t-w-o-r-k could
mean "importance classification" and n-c-n could mean "cycling route
of national importance" and we can all go home happy.

After all, the letters "ncn" is a historical accident. I thought
sustrans called each route something like NCN 4, when it turned out
they call them NCR 4 (see wikipedia -
http://en.wikipedia.org/wiki/NCR_4 ). The "lcn" was - despite some
revisionist history that I've been 100% part of - clearly started as
the London Cycle Network, and the s/London/local/ bit was revisionism
on my part to head off arguments. The network tag seemed appropriate
when all these ncn, lcn, rcn were supposedly each ending in the work
"network", but as soon as someone asked about a standalone local route
then I said don't worry about it, just use lcn, nobody cares whether a
route is part of a larger network or not.

And all over the world people are getting along fine with the
ambiguities. Perhaps when all the tags are meaningless foreign words
people worry less about them.

So don't let the repeated use of the letters n-e-t-w-o-r-k get in the
way of mapping!

Cheers,
Andy
