I would like to map some foot paths that were observed that allow land access to wooded islands. These are only visible at low tide. What tag should I use to indicate their temporary availability? tidal=yes seems to be used only for water areas.

It occurred to me that there are some famous castles in Europe that are only accessible at low tide. I looked one up in OSM, and I see even these are not using special tags for tidal access. They put the information in the name (gasp!) http://www.openstreetmap.org/way/79577445

Your link and this one both put tide warnings in the name box which do warn many map browsers although this method is not liked by many. http://www.openstreetmap.org/#map=17/50.12027/-5.47646

Or indeed this one http://www.openstreetmap.org/way/177923987. In the absence of explicit rendering for tidal areas this is probably sensible.

One possible way of doing this would be to use the conditional restriction scheme and invent (and document) values for low/high tide.

There is a reasonably well used tag of tidal=yes which can be applied to any element which is likely to be covered by water at some phase of the tides.

This is the minimum required, and I think rather less elaborate than using conditional restrictions. The main issue at the moment is that I doubt if people consume this tag along with highways, it certainly has not been added on some of the obvious candidates.
