SAX doesn't actually specify what should happen when you
try to use it.  I think a good practice would be to report
an error when you try to _run_ with it, and in fact I'll
check in a fix to make that happen.  (I can all to easily
imagine code going from default true/false to false/true
by going through false/false instead of true/true, and
there's no reason to treat that as an error.)
