I used an 'intermittent=yes' tag for a county-wide import I did. I remember
it as being an official tag, but when I can't find the documentation now, so
it's likely that I am simply misremembering. There isn't support for the tag
from Mapnik or Osmarender, so if there's another tag that does have render
support, I'd like to know too.
