Osmose report "missing tag
intermittent without waterway, natural=^(water|spring)$, landuse=^(basin|reservoir)$ or ford=yes" of correcting a flagged typo in intermittent in a global report. Comparing to tidal flats I know other side of the ocean, the only difference seems to be the additional 'intermittent' tag used this side on all the same type of areas, no waterway= anywhere. Possibly a false positive. 'intertidal' is how the description of these types of coastal grounds.
