At some point we'll need to deal with that, if future standards or
non-standard extensions from implementors add new fields and we wish
for existing scripts to continue to work.
That said, I think it will be extremely confusing to developers if
these ostensibly-boolean fields are really tri-state (true, false,
unspecified), so it seems like they should default to one of the true
or false behaviours?
