[Talk-transit] NaPTAN Merging Guidelines

Thank you very much for your efforts on this, Thomas, and everyone
else involved - I've been waiting for the London import for a while,
and it's fantastic to see this data in OSM!

I have one "bug" to report: Is it possible that special characters are
being dropped from the stop names during the import? For example:

 <node id="469789137" lat="51.5122005" lon="-0.1420652" version="1"
changeset="2177128" user="NaPTAN" uid="104459" visible="true"
    <tag k="name" v="Conduit Street  Saville Row"/>
    <tag k="naptan:CommonName" v="Conduit Street  Saville Row"/>

TfL refers to this as "Conduit Street / Saville Row", so it seems the
"/" characters are going missing somewhere?

Also, I'm curious whether, in addition to the bus stop data, NaPTAN
contains precise locations for Underground station exits, and if so,
whether there is any plan to import these? OSM often contains only one
node for stations that have multiple exits, and in some cases the node
is ambiguously placed such that it isn't clear which street (or which
side of the street) an exit is on. This level of precision does become
significant when producing walking maps/directions...
