Not as far as I'm concerned, no. It's pretty tedious to tag that way.
(it's pretty tedious to write the rendering rules too, but there's a
fewer number of people affected). If I have 400 toucan crossings to
tag, how do you think I'd prefer to do it?
If someone was to suggest one-tag methods that mollified those who
don't want to learn new words, then I'd prefer that. But in the
interests of treating everyone equally, maybe *nobody* should
understand the values, and ensure that you can't look them up on
wikipedia or in a dictionary?
PS your definition of pelican crossing is wrong, it's not for cyclists.
PPS I'm sticking to crossing=toucan, for those who haven't gathered my
point, until someone comes up with something *better*.
