In [1], I mentioned the use of | in the :lanes tagging scheme, but the 
"OR" use in opening_hours hadn't occurred to me. That makes an even 
stronger argument to avoid overloading this character. The operator " to 
" (with a space on either side) is already being used in several keys as 
an optional, unambiguous range operator where either end of the range 
could contain a hyphen.
