The list delivered this and never kept it. What survives is what the reply below quoted of it.
I don't know about that; GW uses addresses/coordinates' subtext elsewhere.
However, I think this particular encoding is not right because it has
ridiculous precision and insufficient address space to cover 180 degrees
nor 24 hours. Moving the decimal to the right helps but leaves us with out
of range coordinates; some positions can have both.
