Hi Minko,

I am sorry for this awfully late reply.

Your suggestion of replacing the 0x06 with 0x0d makes sense, provided 
that it is routeable and does not imply bicycle=no. (In Finland, 
bicycling up to 20 km/h is allowed on pedestrian areas.)

>a suggestion could be to change this into 0x0d or the same as footway, 0x16

How would you identify a footway? There is some path/cycleway/footway 
controversy and ambiguity going on. Something like this?

highway=footway & bicycle=(yes|designated|permissive|official) [ 0x16 ]
highway=footway [ 0x0d ] # other cases than the above
highway=path & bicycle=no [ 0x0d ]
highway=path & bicycle!=no [ 0x16 ]
highway=cycleway [ 0x16 ]

Right, it could be useful to distinguish cycleways (or 
foot-and-cycleways) from foot-only ways.

I am a little reserved about this, but I agree that this could be useful 
with a TYP file.

According to 
http://wiki.openstreetmap.org/wiki/Editing_OSM_Map_On_Garmin/Area_Types 
the 0x20 could work, but I would have to test it.

There is no natural=beach in the default style. What did you have in 
mind?

I can help with a Finnish translation. How would this TYP file be 
maintained? Is there some editable (text) format and an editor that is 
free software? Quite a while back, I was toying with the idea of 
composing a TYP file from an assembler source file, but I never got 
around to completing it.

Best regards,
