This is a good approach: let's see if it meets the
criteria for infinitely malleable...
1) there is a distinguished null value
yes, you can just leave out booleans, and
say "case=,' for an empty value.
2) obsolete options can be ignored
3) new options can be added asynchronoulsy
4) new, as yet unsupported options can be ignored
5) serious incompatability can be signalled
yes, version= will do the job.
I'd go for it!
