Add generator expressions that combine and use boolean test results: $<0:...> = empty string (ignores "...") $<1:...> = content of "..." $<AND:?[,?]...> = '1' if all '?' are '1', else '0' $<OR:?[,?]...> = '0' if all '?' are '0', else '1' $<NOT:?> = '0' if '?' is '1', else '1' These will be useful to evaluate (future) boolean query expressions and condition content on the results. Include tests and documentation.
